Overview

An API client for Lambda. To construct a client, you need to configure a :region and :credentials.

client = Aws::Lambda::Client.new(
  region: region_name,
  credentials: credentials,
  # ...
)

For details on configuring region and credentials see the developer guide.

See #initialize for a full list of supported configuration options.

Parameters:

  • options (Hash)

Options Hash (options):

  • :plugins (Array<Seahorse::Client::Plugin>) — default: []] —

    A list of plugins to apply to the client. Each plugin is either a class name or an instance of a plugin class.

  • :credentials (required, Aws::CredentialProvider) —

    Your AWS credentials used for authentication. This can be any class that includes and implements Aws::CredentialProvider, or instance of any one of the following classes:

    • Aws::Credentials - Used for configuring static, non-refreshing credentials.

    • Aws::SharedCredentials - Used for loading static credentials from a shared file, such as ~/.aws/config.

    • Aws::AssumeRoleCredentials - Used when you need to assume a role.

    • Aws::AssumeRoleWebIdentityCredentials - Used when you need to assume a role after providing credentials via the web.

    • Aws::SSOCredentials - Used for loading credentials from AWS SSO using an access token generated from aws login.

    • Aws::ProcessCredentials - Used for loading credentials from a process that outputs to stdout.

    • Aws::InstanceProfileCredentials - Used for loading credentials from an EC2 IMDS on an EC2 instance.

    • Aws::ECSCredentials - Used for loading credentials from instances running in ECS.

    • Aws::CognitoIdentityCredentials - Used for loading credentials from the Cognito Identity service.

    When :credentials are not configured directly, the following locations will be searched for credentials:

    • Aws.config[:credentials]

    • The :access_key_id, :secret_access_key, :session_token, and :account_id options.

    • ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY'], ENV['AWS_SESSION_TOKEN'], and ENV['AWS_ACCOUNT_ID'].

    • ~/.aws/credentials

    • ~/.aws/config

    • EC2/ECS IMDS instance profile - When used by default, the timeouts are very aggressive. Construct and pass an instance of Aws::InstanceProfileCredentials or Aws::ECSCredentials to enable retries and extended timeouts. Instance profile credential fetching can be disabled by setting ENV['AWS_EC2_METADATA_DISABLED'] to true.

  • :region (required, String) —

#add_layer_version_permission(params = {}) ⇒ Types::AddLayerVersionPermissionResponse

Adds permissions to the resource-based policy of a version of an Lambda layer. Use this action to grant layer usage permission to other accounts. You can grant permission to a single account, all accounts in an organization, or all Amazon Web Services accounts.

To revoke permission, call RemoveLayerVersionPermission with the statement ID that you specified when you added it.

Examples:

Example: To add permissions to a layer version


# The following example grants permission for the account 223456789012 to use version 1 of a layer named my-layer.

resp = client.add_layer_version_permission({
  action: "lambda:GetLayerVersion", 
  layer_name: "my-layer", 
  principal: "223456789012", 
  statement_id: "xaccount", 
  version_number: 1, 
})

resp.to_h outputs the following:
{
  revision_id: "35d87451-f796-4a3f-a618-95a3671b0a0c", 
  statement: "{\"Sid\":\"xaccount\",\"Effect\":\"Allow\",\"Principal\":{\"AWS\":\"arn:aws:iam::223456789012:root\"},\"Action\":\"lambda:GetLayerVersion\",\"Resource\":\"arn:aws:lambda:us-east-2:123456789012:layer:my-layer:1\"}", 
}

})

Response structure


resp.statement #=> String
resp.revision_id #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :layer_name (required, String) —

    The name or Amazon Resource Name (ARN) of the layer.

  • :version_number (required, Integer) —

    The version number.

  • :statement_id (required, String) —

    An identifier that distinguishes the policy from others on the same layer version.

  • :action (required, String) —

    The API action that grants access to the layer. For example, lambda:GetLayerVersion.

  • :principal (required, String) —

    An account ID, or * to grant layer usage permission to all accounts in an organization, or all Amazon Web Services accounts (if organizationId is not specified). For the last case, make sure that you really do want all Amazon Web Services accounts to have usage permission to this layer.

  • :organization_id (String) —

    With the principal set to *, grant permission to all accounts in the specified organization.

  • :revision_id (String) —

    Only update the policy if the revision ID matches the ID specified. Use this option to avoid modifying a policy that has changed since you last read it.

end

#add_permission(params = {}) ⇒ Types::AddPermissionResponse

Grants a principal permission to use a function. You can apply the policy at the function level, or specify a qualifier to restrict access to a single version or alias. If you use a qualifier, the invoker must use the full Amazon Resource Name (ARN) of that version or alias to invoke the function. Note: Lambda does not support adding policies to version $LATEST.

To grant permission to another account, specify the account ID as the Principal. To grant permission to an organization defined in Organizations, specify the organization ID as the PrincipalOrgID. For Amazon Web Services services, the principal is a domain-style identifier that the service defines, such as s3.amazonaws.com or sns.amazonaws.com. For Amazon Web Services services, you can also specify the ARN of the associated resource as the SourceArn. If you grant permission to a service principal without specifying the source, other accounts could potentially configure resources in their account to invoke your Lambda function.

This operation adds a statement to a resource-based permissions policy for the function. For more information about function policies, see Using resource-based policies for Lambda.

Examples:

Example: To grant Amazon S3 permission to invoke a function


# The following example adds permission for Amazon S3 to invoke a Lambda function named my-function for notifications from
# a bucket named my-bucket-1xpuxmplzrlbh in account 123456789012.

resp = client.add_permission({
  action: "lambda:InvokeFunction", 
  function_name: "my-function", 
  principal: "s3.amazonaws.com", 
  source_account: "123456789012", 
  source_arn: "arn:aws:s3:::my-bucket-1xpuxmplzrlbh/*", 
  statement_id: "s3", 
})

resp.to_h outputs the following:
{
  statement: "{\"Sid\":\"s3\",\"Effect\":\"Allow\",\"Principal\":{\"Service\":\"s3.amazonaws.com\"},\"Action\":\"lambda:InvokeFunction\",\"Resource\":\"arn:aws:lambda:us-east-2:123456789012:function:my-function\",\"Condition\":{\"StringEquals\":{\"AWS:SourceAccount\":\"123456789012\"},\"ArnLike\":{\"AWS:SourceArn\":\"arn:aws:s3:::my-bucket-1xpuxmplzrlbh\"}}}", 
}

Example: To grant another account permission to invoke a function

resp = client.add_permission({
  action: "lambda:InvokeFunction", 
  function_name: "my-function", 
  principal: "223456789012",

    • Partial ARN – 123456789012:function:my-function.

    You can append a version number or alias to any of the formats. The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

  • :statement_id (required, String) —

    A statement identifier that differentiates the statement from others in the same policy.

  • :action (required, String) —

    Indicates whether the permission applies when the function is invoked through a function URL.

  • :source_account (String) —

    For Amazon Web Services service, the ID of the Amazon Web Services account that owns the resource. Use this together with SourceArn to ensure that the specified account owns the resource. It is possible for an Amazon S3 bucket to be deleted by its owner and recreated by another account.

  • :event_source_token (String) —

    For Alexa Smart Home functions, a token that the invoker must supply.

  • :qualifier (String) —

    Specify a version or alias to add permissions to a published version of the function.

#checkpoint_durable_execution(params = {}) ⇒ Types::CheckpointDurableExecutionResponse

Saves the progress of a durable function execution during runtime. This API is used by the Lambda durable functions SDK to checkpoint completed steps and schedule asynchronous operations. You typically don't need to call this API directly as the SDK handles checkpointing automatically.

Each checkpoint operation consumes the current checkpoint token and returns a new one for the next checkpoint. This ensures that checkpoints are applied in the correct order and prevents duplicate or out-of-order state updates.

Examples:

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :durable_execution_arn (required, String) —

    The Amazon Resource Name (ARN) of the durable execution.

  • :checkpoint_token (required, String) —

    A unique token that identifies the current checkpoint state. This token is provided by the Lambda runtime and must be used to ensure checkpoints are applied in the correct order. Each checkpoint operation consumes this token and returns a new one.

  • :updates (Array<Types::OperationUpdate>) —

    An array of state updates to apply during this checkpoint. Each update represents a change to the execution state, such as completing a step, starting a callback, or scheduling a timer. Updates are applied atomically as part of the checkpoint operation.

  • :client_token (String) —

    An optional idempotency token to ensure that duplicate checkpoint requests are handled correctly. If provided, Lambda uses this token to detect and handle duplicate requests within a 15-minute window.

    A suitable default value is auto-generated. You should normally not need to pass this option.**

#create_alias(params = {}) ⇒ Types::AliasConfiguration

Creates an alias for a Lambda Event Function version. Use aliases to provide clients with a function identifier that you can update to invoke a different version.

You can also map an alias to split invocation requests between two versions. Use the RoutingConfig parameter to specify a second version and the percentage of invocation requests that it receives.

Examples:

Example: To create an alias for a Lambda function


# The following example creates an alias named LIVE that points to version 1 of the my-function Lambda function.

resp = client.create_alias({
  description: "alias for live version of function", 
  function_name: "my-function", 
  function_version: "1", 
  name: "LIVE", 
})

resp.to_h outputs the following:
{
  alias_arn: "arn:aws:lambda:us-east-2:123456789012:function:my-function:LIVE", 
  description: "alias for live version of function", 
  function_version: "1", 
  name: "LIVE", 
  revision_id: "873282ed-xmpl-4dc8-a069-d0c647e470c6",

#create_event_source_mapping(params = {}) ⇒ Types::EventSourceMappingConfiguration

Creates a mapping between an event source and an Lambda Event Function. Lambda reads items from the event source and invokes the function.

For details about how to configure different event sources, see the following topics.

The following error handling options are available for stream sources (DynamoDB, Kinesis, Amazon MSK, and self-managed Apache Kafka):

  • BisectBatchOnFunctionError – If the function returns an error, split the batch in two and retry.

  • MaximumRecordAgeInSeconds – Discard records older than the specified age. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires

  • MaximumRetryAttempts – Discard records after the specified number of retries. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires.

  • OnFailure – Send discarded records to an Amazon SQS queue, Amazon SNS topic, Kafka topic, or Amazon S3 bucket. For more information, see Adding a destination.

The following option is available only for DynamoDB and Kinesis event sources:

  • ParallelizationFactor – Process multiple batches from each shard concurrently.

^

For information about which configuration parameters apply to each event source, see the following topics.

Examples:

    ({})

Options Hash (params):

  • :event_source_arn (String) —

    The Amazon Resource Name (ARN) of the event source.

    • Amazon Kinesis – The ARN of the data stream or a stream consumer.

    • Amazon DynamoDB Streams – The ARN of the stream.

    • Amazon Simple Queue Service – The ARN of the queue.

    • Amazon Managed Streaming for Apache Kafka – The ARN of the cluster or the ARN of the VPC connection (for cross-account event source mappings).

    • Amazon MQ – The ARN of the broker.

    • Amazon DocumentDB – The ARN of the DocumentDB change stream.

  • :function_name (required, String) —

    The name or ARN of the Lambda function.

    Name formats

    • Function name – MyFunction.

    • Function ARN – arn:aws:lambda:us-west-2:123456789012:function:MyFunction.

    • Version or Alias ARN – arn:aws:lambda:us-west-2:123456789012:function:MyFunction:PROD.

    • Partial ARN – 123456789012:function:MyFunction.

    The length constraint applies only to the full ARN. If you specify only the function name, it's limited to 64 characters in length.

  • :enabled (Boolean) —

    When true, the event source mapping is active. When false, Lambda pauses polling and invocation.

    Default: True

  • :batch_size (Integer) —

    The maximum number of records in each batch that Lambda pulls from your stream or queue and sends to your function. Lambda passes all of the records in the batch to the function in a single call, up to the payload limit for synchronous invocation (6 MB).

    • Amazon Kinesis – Default 100. Max 10,000.

    • Amazon DynamoDB Streams – Default 100. Max 10,000.

    • Amazon Simple Queue Service – Default 10. For standard queues the max is 10,000. For FIFO queues the max is 10.

    • Amazon Managed Streaming for Apache Kafka – Default 100. Max 10,000.

    • Self-managed Apache Kafka – Default 100. Max 10,000.

    • Amazon MQ (ActiveMQ and RabbitMQ) – Default 100. Max 10,000.

    • DocumentDB – Default 100. Max 10,000.

  • :filter_criteria (Types::FilterCriteria) —

    An object that defines the filter criteria that determine whether Lambda should process an event. For more information, see Lambda event filtering.

  • :kms_key_arn (String) —

    The ARN of the Key Management Service (KMS) customer managed key that Lambda uses to encrypt your function's filter criteria. By default, Lambda does not encrypt your filter criteria object. Specify this property to encrypt data using your own customer managed key.

  • :metrics_config (Types::EventSourceMappingMetricsConfig) —

    The metrics configuration for your event source. For more information, see Event source mapping metrics.

  • :logging_config (Types::EventSourceMappingLoggingConfig) — default: Amazon MSK, and self-managed Apache Kafka only —

    The logging configuration for your event source. For more information, see Event source mapping logging.

  • :scaling_config (Types::ScalingConfig) — default: Amazon SQS only —

    The scaling configuration for the event source. For more information, see Configuring maximum concurrency for Amazon SQS event sources.

  • :maximum_batching_window_in_seconds (Integer) —

    The maximum amount of time, in seconds, that Lambda spends gathering records before invoking the function. You can configure MaximumBatchingWindowInSeconds to any value from 0 seconds to 300 seconds in increments of seconds.

    For Kinesis, DynamoDB, and Amazon SQS event sources, the default batching window is 0 seconds. For Amazon MSK, Self-managed Apache Kafka, Amazon MQ, and DocumentDB event sources, the default batching window is 500 ms. Note that because you can only change MaximumBatchingWindowInSeconds in increments of seconds, you cannot revert back to the 500 ms default batching window after you have changed it. To restore the default batching window, you must create a new event source mapping.

    Related setting: For Kinesis, DynamoDB, and Amazon SQS event sources, when you set BatchSize to a value greater than 10, you must set MaximumBatchingWindowInSeconds to at least 1.

  • :parallelization_factor (Integer) — default: Kinesis and DynamoDB Streams only —

    The number of batches to process from each shard concurrently.

  • :starting_position (String) —

    The position in a stream from which to start reading. Required for Amazon Kinesis and Amazon DynamoDB Stream event sources. AT_TIMESTAMP is supported only for Amazon Kinesis streams, Amazon DocumentDB, Amazon MSK, and self-managed Apache Kafka.

  • :starting_position_timestamp (Time, DateTime, Date, Integer, String) —

    With StartingPosition set to AT_TIMESTAMP, the time from which to start reading. StartingPositionTimestamp cannot be in the future.

  • :destination_config (Types::DestinationConfig) — default: Kinesis, DynamoDB Streams, Amazon MSK, and self-managed Apache Kafka —

    A configuration object that specifies the destination of an event after Lambda processes it.

  • :maximum_record_age_in_seconds (Integer) — default: Kinesis, DynamoDB Streams, Amazon MSK, and self-managed Apache Kafka —

    Discard records older than the specified age. The default value is infinite (-1).

  • :bisect_batch_on_function_error (Boolean) — default: Kinesis, DynamoDB Streams, Amazon MSK, and self-managed Apache Kafka —

    If the function returns an error, split the batch in two and retry.

  • :maximum_retry_attempts (Integer) — default: Kinesis, DynamoDB Streams, Amazon MSK, and self-managed Apache Kafka —

    Discard records after the specified number of retries. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires.

  • :tags (Hash<String,String>) —

    A list of tags to apply to the event source mapping.

  • :tumbling_window_in_seconds (Integer) — default: Kinesis and DynamoDB Streams only —

    The duration in seconds of a processing window for DynamoDB and Kinesis Streams event sources. A value of 0 seconds indicates no tumbling window.

  • :topics (Array<String>) —

    The name of the Kafka topic.

  • :queues (Array<String>) — default: MQ —

    The name of the Amazon MQ broker destination queue to consume.

  • :source_access_configurations (Array<Types::SourceAccessConfiguration>) —

    An array of authentication protocols or VPC components required to secure your event source.

    Specific configuration settings for an Amazon Managed Streaming for Apache Kafka (Amazon MSK) event source.

  • :self_managed_kafka_event_source_config (Types::SelfManagedKafkaEventSourceConfig) —

    Specific configuration settings for a self-managed Apache Kafka event source.

  • :document_db_event_source_config (Types::DocumentDBEventSourceConfig) —

    Specific configuration settings for a DocumentDB event source.

  • :provisioned_poller_config (Types::ProvisionedPollerConfig) — default: Amazon SQS, Amazon MSK, and self-managed Apache Kafka only —

#create_function(params = {}) ⇒ Types::FunctionConfiguration

Creates a Lambda Event Function. To create a function, you need a deployment package and an execution role. The deployment package is a .zip file archive or container image that contains your function code. The execution role grants the function permission to use Amazon Web Services services, such as Amazon CloudWatch Logs for log streaming and X-Ray for request tracing.

If the deployment package is a container image, then you set the package type to Image. For a container image, the code property must include the URI of a container image in the Amazon ECR registry. You do not need to specify the handler and runtime properties.

If the deployment package is a .zip file archive, then you set the package type to Zip. For a .zip file archive, the code property specifies the location of the .zip file. You must also specify the handler and runtime properties. The code in the deployment package must be compatible with the target instruction set architecture of the function (x86-64 or arm64). If you do not specify the architecture, then the default value is x86-64.

When you create a function, Lambda provisions an instance of the function and its supporting resources. If your function connects to a VPC, this process can take a minute or so. During this time, you can't invoke or modify the function. The State, StateReason, and StateReasonCode fields in the response from GetFunctionConfiguration indicate when the function is ready to invoke. For more information, see Lambda function states.

A function has an unpublished version, and can have published versions and aliases. The unpublished version changes when you update your function's code and configuration. A published version is a snapshot of your function code and configuration that can't be changed. An alias is a named resource that maps to a version, and can be changed to map to a different version. Use the Publish parameter to create version 1 of your function from its initial configuration.

The other parameters let you configure version-specific and function-level settings. You can modify version-specific settings later with UpdateFunctionConfiguration. Function-level settings apply to both the unpublished and published versions of the function, and include tags (TagResource) and per-function concurrency limits (PutFunctionConcurrency).

You can use code signing if your deployment package is a .zip file archive. To enable code signing for this function, specify the ARN of a code-signing configuration. When a user attempts to deploy a code package with UpdateFunctionCode, Lambda checks that the code package has a valid signature from a trusted publisher. The code-signing configuration includes set of signing profiles, which define the trusted publishers for this function.

If another Amazon Web Services account or an Amazon Web Services service invokes your function, use AddPermission to grant permission by creating a resource-based Identity and Access Management (IAM) policy. You can grant permissions at the function level, on a version, or on an alias.

To invoke your function directly, use Invoke. To invoke your function in response to events in other Amazon Web Services services, create an event source mapping (CreateEventSourceMapping), or configure a function trigger in the other service. For more information, see Invoking Lambda functions.

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :function_name (required, String) —

    The name or ARN of the Lambda function.

    Name formats

    • Function name – my-function.

    • Function ARN – arn:aws:lambda:us-west-2:123456789012:function:my-function.

    • Partial ARN – 123456789012:function:my-function.

    The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

  • :runtime (String) —

    The identifier of the function's runtime. Runtime is required if the deployment package is a .zip file archive. Specifying a runtime results in an error if you're deploying a function using a container image.

    The following list includes deprecated runtimes. Lambda blocks creating new functions and updating existing functions shortly after each runtime is deprecated. For more information, see Runtime use after deprecation.

    For a list of all currently supported runtimes, see Supported runtimes.

  • :role (required, String) —

    The Amazon Resource Name (ARN) of the function's execution role.

  • :handler (String) —

    The name of the method within your code that Lambda calls to run your function. Handler is required if the deployment package is a .zip file archive. The format includes the file name. It can also include namespaces and other qualifiers, depending on the runtime. For more information, see Lambda programming model.

  • :code (required, Types::FunctionCode) —

    The code for the function.

  • :description (String) —

    A description of the function.

  • :timeout (Integer) —

    The amount of time (in seconds) that Lambda allows a function to run before stopping it. The default is 3 seconds, and the maximum allowed value is 900 seconds. For functions using Lambda Managed Instances, asynchronous invocations and event source mapping invocations (except Amazon MQ and Amazon DocumentDB) support a maximum allowed value of 5,400 seconds (90 minutes). For more information, see Lambda execution environment.

  • :memory_size (Integer) —

    The amount of memory available to the function at runtime. Increasing the function memory also increases its CPU allocation. The default value is 128 MB. The value can be any multiple of 1 MB.

  • :publish (Boolean) —

    Set to true to publish the first version of the function during creation.

  • :publish_to (String) —

    Specifies where to publish the function version or configuration.

  • :vpc_config (Types::VpcConfig) —

    For network connectivity to Amazon Web Services resources in a VPC, specify a list of security groups and subnets in the VPC. When you connect a function to a VPC, it can access resources and the internet only through that VPC. For more information, see Configuring a Lambda function to access resources in a VPC.

  • :package_type (String) —

    The type of deployment package. Set to Image for container image and set to Zip for .zip file archive.

  • :dead_letter_config (Types::DeadLetterConfig) —

    A dead-letter queue configuration that specifies the queue or topic where Lambda sends asynchronous events when they fail processing. For more information, see Dead-letter queues.

  • :environment (Types::Environment) —

    Environment variables that are accessible from function code during execution.

#delete_function(params = {}) ⇒ Types::DeleteFunctionResponse

Deletes a Lambda Event Function. To delete a specific function version, use the Qualifier parameter. Otherwise, all versions and aliases are deleted. This doesn't require the user to have explicit permissions for DeleteAlias.

A deleted Lambda function cannot be recovered. Ensure that you specify the correct function name and version before deleting.

To delete Lambda event source mappings that invoke a function, use DeleteEventSourceMapping. For Amazon Web Services services and resources that invoke your function directly, delete the trigger in the service where you originally configured it.

Examples:

Example: To delete a version of a Lambda function


# The following example deletes version 1 of a Lambda function named my-function.

resp = client.delete_function({
  function_name: "my-function", 
  qualifier: "1", 
})

Request syntax with placeholder values


resp = client.delete_function({
  function_name: "NamespacedFunctionName", # required
  qualifier: "NumericLatestPublishedOrAliasQualifier",
})

Response structure


resp.status_code #=> Integer

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :function_name (required, String) —

    The name or ARN of the Lambda function or version.

    • Function name – my-function (name-only), my-function:1 (with version).

    • Function ARN – arn:aws:lambda:us-west-2:123456789012:function:my-function.

    • Partial ARN – 123456789012:function:my-function.

    You can append a version number or alias to any of the formats. The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

  • :qualifier (String) —

    Specify a version to delete. You can't delete a version that an alias references.

#get_durable_execution_state(params = {}) ⇒ Types::GetDurableExecutionStateResponse

Retrieves the current execution state required for the replay process during durable function execution. This API is used by the Lambda durable functions SDK to get state information needed for replay. You typically don't need to call this API directly as the SDK handles state management automatically.

The response contains operations ordered by start sequence number in ascending order. Completed operations with children don't include child operation details since they don't need to be replayed.

The returned response is a pageable response and is Enumerable. For details on usage see PageableResponse.

Examples:

#invoke(params = {}) ⇒ Types::InvocationResponse

Invokes a Lambda Event Function. You can invoke a function synchronously (and wait for the response), or asynchronously. By default, Lambda invokes your function synchronously (i.e. theInvocationType is RequestResponse). To invoke a function asynchronously, set InvocationType to Event. Lambda passes the ClientContext object to your function for synchronous invocations only.

For synchronous invocations, the maximum payload size is 6 MB. For asynchronous invocations, the maximum payload size is 1 MB.

For synchronous invocation, details about the function response, including errors, are included in the response body and headers. For either invocation type, you can find more information in the execution log and trace.

When an error occurs, your function may be invoked multiple times. Retry behavior varies by error type, client, event source, and invocation type. For example, if you invoke a function asynchronously and it returns an error, Lambda executes the function up to two more times. For more information, see Error handling and automatic retries in Lambda.

For asynchronous invocation, Lambda adds events to a queue before sending them to your function. If your function does not have enough capacity to keep up with the queue, events may be lost. Occasionally, your function may receive the same event multiple times, even if no error occurs. To retain events that were not processed, configure your function with a dead-letter queue.

The status code in the API response doesn't reflect function errors. Error codes are reserved for errors that prevent your function from executing, such as permissions errors, quota errors, or issues with your function's code and configuration. For example, Lambda returns TooManyRequestsException if running the function would cause you to exceed a concurrency limit at either the account level (ConcurrentInvocationLimitExceeded) or function level (ReservedFunctionConcurrentInvocationLimitExceeded).

For functions with a long timeout, your client might disconnect during synchronous invocation while it waits for a response. Configure your HTTP client, SDK, firewall, proxy, or operating system to allow for long connections with timeout or keep-alive settings.

This operation requires permission for the lambda:InvokeFunction action. For details on how to set up permissions for cross-account invocations, see Granting function access to other accounts.

Examples:

Example: To invoke a Lambda function


# The following example invokes version 1 of a function named my-function with an empty event payload.

resp = client.invoke({
  durable_execution_name: "myExecution", 
  function_name: "my-function", 
  invocation_type: "Event", 
  payload: "{}", 
  qualifier: "1", 
})

resp.to_h outputs the following:
{
  payload: "200 SUCCESS", 
  status_code: 200, 
}

Example: To invoke a Lambda function asynchronously


# The following example invokes version 1 of a function named my-function asynchronously.

resp = client.invoke({
  function_name: "my-function", 
  invocation_type: "Event", 
  payload: "{}", 
  qualifier: "1", 
})

resp.to_h outputs the following:
{
  payload: "", 
  status_code: 202, 
}

Request syntax with placeholder values


resp = client.invoke({
  function_name: "NamespacedFunctionName", # required
  invocation_type: "Event", # accepts Event, RequestResponse, DryRun
  log_type: "None", # accepts None, Tail
  client_context: "String",
  durable_execution_name: "DurableExecutionName",
  payload: "data",
  qualifier: "NumericLatestPublishedOrAliasQualifier",
  tenant_id: "TenantId",
})

Response structure


resp.status_code #=> Integer
resp.function_error #=> String
resp.log_result #=> String
resp.payload #=> String
resp.executed_version #=> String
resp.durable_execution_arn #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :function_name (required, String) —

    The name or ARN of the Lambda function, version, or alias.

    Name formats

    • Function name – my-function (name-only), my-function:v1 (with alias).

    • Function ARN – arn:aws:lambda:us-west-2:123456789012:function:my-function.

    • Partial ARN – 123456789012:function:my-function.

    You can append a version number or alias to any of the formats. The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

  • :invocation_type (String) —

    Choose from the following options.

    • RequestResponse (default) – Invoke the function synchronously. Keep the connection open until the function returns a response or times out. The API response includes the function response and additional data.

    • Event – Invoke the function asynchronously. Send events that fail multiple times to the function's dead-letter queue (if one is configured). The API response only includes a status code.

    • DryRun – Validate parameter values and verify that the user or role has permission to invoke the function.

  • :log_type (String) —

    Set to Tail to include the execution log in the response. Applies to synchronously invoked functions only.

  • :client_context (String) —

    Up to 3,583 bytes of base64-encoded data about the invoking client to pass to the function in the context object. Lambda passes the ClientContext object to your function for synchronous invocations only.

  • :durable_execution_name (String) —

    A unique name for the durable execution. If you invoke a durable function using a name that already exists with the same payload, Lambda returns the existing execution instead of creating a duplicate. If the payload differs, Lambda returns a DurableExecutionAlreadyStartedException error.

    If not specified, Lambda generates a unique identifier automatically. For more information, see Execution names.

  • :payload (String, StringIO, File) —

    The JSON that you want to provide to your Lambda function as input. The maximum payload size is 6 MB for synchronous invocations and 1 MB for asynchronous invocations.

    You can enter the JSON directly. For example, --payload '{ "key": "value" }'. You can also specify a file path. For example, --payload file://payload.json.

  • :qualifier (String) —

    Specify a version or alias to invoke a published version of the function.

  • :tenant_id (String) —

    The identifier of the tenant in a multi-tenant Lambda function.

#invoke_async(params = {}) ⇒ Types::InvokeAsyncResponse

For asynchronous function invocation, use Invoke.

Invokes a function asynchronously.

The payload limit is 256KB. For larger payloads, for up to 1MB, use Invoke.

If you do use the InvokeAsync action, note that it doesn't support the use of X-Ray active tracing. Trace ID is not propagated to the function, even if X-Ray active tracing is turned on.

Examples:

Example: To invoke a Lambda function asynchronously


# The following example invokes a Lambda function asynchronously

resp = client.invoke_async({

#invoke_with_response_stream(params = {}) ⇒ Types::InvokeWithResponseStreamResponse

Configure your Lambda Event Functions to stream response payloads back to clients. For more information, see Configuring a Lambda function to stream responses.

This operation requires permission for the lambda:InvokeFunction action. For details on how to set up permissions for cross-account invocations, see Granting function access to other accounts.

Examples:

EventStream Operation Example


# You can process the event once it arrives immediately, or wait until the
# full response is complete and iterate through the eventstream enumerator.

# To interact with event immediately, you need to register invoke_with_response_stream
# with callbacks. Callbacks can be registered for specific events or for all
# events, including error events.

# Callbacks can be passed into the `:event_stream_handler` option or within a
# block statement attached to the #invoke_with_response_stream call directly. Hybrid
# pattern of both is also supported.

# `:event_stream_handler` option takes in either a Proc object or
# Aws::Lambda::EventStreams::InvokeWithResponseStreamResponseEvent object.

# Usage pattern a): Callbacks with a block attached to #invoke_with_response_stream
# Example for registering callbacks for all event types and an error event
client.invoke_with_response_stream(
  # params input
) do |stream|
  stream.on_error_event do |event|
    # catch unmodeled error event in the stream
    raise event
    # => Aws::Errors::EventError
    # event.event_type => :error
    # event.error_code => String
    # event.error_message => String
  end

  stream.on_event do |event|
    # process all events arrive
    puts event.event_type
    # ...
  end
end

# Usage pattern b): Pass in `:event_stream_handler` for #invoke_with_response_stream
#  1) Create a Aws::Lambda::EventStreams::InvokeWithResponseStreamResponseEvent object
#  Example for registering callbacks with specific events

handler = Aws::Lambda::EventStreams::InvokeWithResponseStreamResponseEvent.new
handler.on_payload_chunk_event do |event|
  event # => Aws::Lambda::Types::PayloadChunk
end
handler.on_invoke_complete_event do |event|
  event # => Aws::Lambda::Types::InvokeComplete
end

client.invoke_with_response_stream(
  # params inputs
  event_stream_handler: handler
)

#  2) Use a Ruby Proc object
#  Example for registering callbacks with specific events
handler = Proc.new do |stream|
  stream.on_payload_chunk_event do |event|
    event # => Aws::Lambda::Types::PayloadChunk
  end
  stream.on_invoke_complete_event do |event|
    event # => Aws::Lambda::Types::InvokeComplete
  end
end

client.invoke_with_response_stream(
  # params inputs
  event_stream_handler: handler
)

#  Usage pattern c): Hybrid pattern of a) and b)
handler = Aws::Lambda::EventStreams::InvokeWithResponseStreamResponseEvent.new
handler.on_payload_chunk_event do |event|
  event # => Aws::Lambda::Types::PayloadChunk
end
handler.on_invoke_complete_event do |event|
  event # => Aws::Lambda::Types::InvokeComplete
end

client.invoke_with_response_stream(
  # params input
  event_stream_handler: handler
) do |stream|
  stream.on_error_event do |event|
    # catch unmodeled error event in the stream
    raise event
    # => Aws::Errors::EventError
    # event.event_type => :error
    # event.error_code => String
    # event.error_message => String
  end
end

# You can also iterate through events after the response complete.
# Events are available at
resp.event_stream # => Enumerator
# For parameter input example, please refer to following request syntax.

#publish_version(params = {}) ⇒ Types::FunctionConfiguration

Creates a version from the current code and configuration of a function. Use versions to create a snapshot of your function code and configuration that doesn't change.

Lambda doesn't publish a version if the function's configuration and code haven't changed since the last version. Use UpdateFunctionCode or UpdateFunctionConfiguration to update the function before publishing a version.

Clients can invoke versions directly or with an alias. To create an alias, use CreateAlias.

Examples:

Example: To publish a version of a Lambda function

#put_function_concurrency(params = {}) ⇒ Types::Concurrency

Sets the maximum number of simultaneous executions for a function, and reserves capacity for that concurrency level.

Concurrency settings apply to the function as a whole, including all published versions and the unpublished version. Reserving concurrency both ensures that your function has capacity to process the specified number of events simultaneously, and prevents it from scaling beyond that level. Use GetFunction to see the current setting for a function.

Use GetAccountSettings to see your Regional concurrency limit. You can reserve concurrency for as many functions as you like, as long as you leave at least 100 simultaneous executions unreserved for functions that aren't configured with a per-function limit. For more information, see Lambda function scaling.

Examples:

Example: To configure a reserved concurrency limit for a function


# The following example configures 100 reserved concurrent executions for the my-function function.

resp = client.put_function_concurrency({
  function_name: "my-function", 
  reserved_concurrent_executions: 100, 
})

resp.to_h outputs the following:
{
  reserved_concurrent_executions: 100, 
}

Request syntax with placeholder values


resp = client.put_function_concurrency({
  function_name: "FunctionName", # required
  reserved_concurrent_executions: 1, # required
})

Response structure


resp.reserved_concurrent_executions #=> Integer

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :function_name (required, String) —

    The name or ARN of the Lambda function.

    Name formats

    • Function name – my-function.

    • Function ARN – arn:aws:lambda:us-west-2:123456789012:function:my-function.

    • Partial ARN – 123456789012:function:my-function.

    The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

  • :reserved_concurrent_executions (required, Integer) —

    The number of simultaneous executions to reserve for the function.

#put_function_event_invoke_config(params = {}) ⇒ Types::FunctionEventInvokeConfig

Configures options for asynchronous invocation on a function, version, or alias. If a configuration already exists for a function, version, or alias, this operation overwrites it. If you exclude any settings, they are removed. To set one option without affecting existing settings for other options, use UpdateFunctionEventInvokeConfig.

By default, Lambda retries an asynchronous invocation twice if the function returns an error. It retains events in a queue for up to six hours. When an event fails all processing attempts or stays in the asynchronous invocation queue for too long, Lambda discards it. To retain discarded events, configure a dead-letter queue with UpdateFunctionConfiguration.

To send an invocation record to a queue, topic, S3 bucket, function, or event bus, specify a destination. You can configure separate destinations for successful invocations (on-success) and events that fail all processing attempts (on-failure). You can configure destinations in addition to or instead of a dead-letter queue.

S3 buckets are supported only for on-failure destinations. To retain records of successful invocations, use another destination type.

Examples:

Example: To configure error handling for asynchronous invocation


# The following example sets a maximum event age of one hour and disables retries for the specified function.

resp = client.put_function_event_invoke_config({
  function_name: "my-function", 
  maximum_event_age_in_seconds: 3600, 
  maximum_retry_attempts: 0, 
})

resp.to_h outputs the following:

#put_function_recursion_config(params = {}) ⇒ Types::PutFunctionRecursionConfigResponse

Sets your function's recursive loop detection configuration.

When you configure a Lambda function to output to the same service or resource that invokes the function, it's possible to create an infinite recursive loop. For example, a Lambda function might write a message to an Amazon Simple Queue Service (Amazon SQS) queue, which then invokes the same function. This invocation causes the function to write another message to the queue, which in turn invokes the function again.

Lambda can detect certain types of recursive loops shortly after they occur. When Lambda detects a recursive loop and your function's recursive loop detection configuration is set to Terminate, it stops your function being invoked and notifies you.

Examples:

Request syntax with placeholder values


resp = client.put_function_recursion_config({
  function_name: "UnqualifiedFunctionName", # required
  recursive_loop: "Allow", # required, accepts Allow, Terminate
})

Response structure


resp.recursive_loop #=> String, one of "Allow", "Terminate"

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :function_name (required, String) —

    The name or ARN of the Lambda function.

    Name formats

    • Function name – my-function.

    • Function ARN – arn:aws:lambda:us-west-2:123456789012:function:my-function.

    • Partial ARN – 123456789012:function:my-function.

    The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

  • :recursive_loop (required, String) —

    If you set your function's recursive loop detection configuration to Allow, Lambda doesn't take any action when it detects your function being invoked as part of a recursive loop. We recommend that you only use this setting if your design intentionally uses a Lambda function to write data back to the same Amazon Web Services resource that invokes it.

    If you set your function's recursive loop detection configuration to Terminate, Lambda stops your function being invoked and notifies you when it detects your function being invoked as part of a recursive loop.

    By default, Lambda sets your function's configuration to Terminate.

    If your design intentionally uses a Lambda function to write data back to the same Amazon Web Services resource that invokes the function, then use caution and implement suitable guard rails to prevent unexpected charges being billed to your Amazon Web Services account. To learn more about best practices for using recursive invocation patterns, see Recursive patterns that cause run-away Lambda functions in Serverless Land.

#put_resource_policy(params = {}) ⇒ Types::PutResourcePolicyResponse

Adds a resource-based policy to a Lambda resource. Resource-based policies grant access to other Amazon Web Services accounts, organizations, or services. Resource-based policies apply to a single Lambda resource (for example, a function, function version, or function alias).

This operation replaces any existing policy on the Lambda resource. If you previously added permissions using the AddPermission operation, the new policy overwrites those permissions.

Examples:

Request syntax with placeholder values


resp = client.put_resource_policy({
  resource_arn: "PolicyResourceArn", # required
  policy: "ResourcePolicy", # required
  revision_id: "RevisionId",
})

Response structure


resp.policy #=> String
resp.revision_id #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :resource_arn (required, String) —

    The Amazon Resource Name (ARN) of the Lambda resource you want to add the policy to. You can use a qualified or an unqualified ARN. The value must be a complete ARN, and the operation does not accept wildcard characters.

  • :policy (required, String) —

    The policy document you want to add to your Lambda resource. This is formatted as a JSON string.

    For more information, see Working with resource-based policies in Lambda in the Lambda Developer Guide.

  • :revision_id (String) —

    The revision ID that the existing policy must match for the replacement to proceed. If the revision ID doesn't match, the operation fails with a PreconditionFailedException error. To retrieve the current revision ID, use the GetResourcePolicy operation.

  function_name: "NamespacedFunctionName", # required
  qualifier: "NumericLatestPublishedOrAliasQualifier",
  update_runtime_on: "Auto", # required, accepts Auto, Manual, FunctionUpdate
  runtime_version_arn: "RuntimeVersionArn",
})

Response structure


resp.update_runtime_on #=> String, one of "Auto", "Manual", "FunctionUpdate"
resp.function_arn #=> String
resp.runtime_version_arn #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :function_name (required, String) —

    The name or ARN of the Lambda function.

    Name formats

    • Function name – my-function.

    • Function ARN – arn:aws:lambda:us-west-2:123456789012:function:my-function.

    • Partial ARN – 123456789012:function:my-function.

    The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

  • :qualifier (String) —

    Specify a version of the function. This can be $LATEST or a published version number. If no value is specified, the configuration for the $LATEST version is returned.

  • :update_runtime_on (required, String) —

    Specify the runtime update mode.

    • Auto (default) - Automatically update to the most recent and secure runtime version using a Two-phase runtime version rollout. This is the best choice for most customers to ensure they always benefit from runtime updates.

    • Function update - Lambda updates the runtime of your function to the most recent and secure runtime version when you update your function. This approach synchronizes runtime updates with function deployments, giving you control over when runtime updates are applied and allowing you to detect and mitigate rare runtime update incompatibilities early. When using this setting, you need to regularly update your functions to keep their runtime up-to-date.

    • Manual - You specify a runtime version in your function configuration. The function will use this runtime version indefinitely. In the rare case where a new runtime version is incompatible with an existing function, this allows you to roll back your function to an earlier runtime version. For more information, see Roll back a runtime version.

  • :runtime_version_arn (String) —

    The ARN of the runtime version you want the function to use.

    This is only required if you're using the Manual runtime update mode.

Returns:

#update_event_source_mapping(params = {}) ⇒ Types::EventSourceMappingConfiguration

Updates an event source mapping. You can change the function that Lambda invokes, or pause invocation and resume later from the same location.

For details about how to configure different event sources, see the following topics.

The following error handling options are available for stream sources (DynamoDB, Kinesis, Amazon MSK, and self-managed Apache Kafka):

  • BisectBatchOnFunctionError – If the function returns an error, split the batch in two and retry.

  • MaximumRecordAgeInSeconds – Discard records older than the specified age. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires

  • MaximumRetryAttempts – Discard records after the specified number of retries. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires.

  • OnFailure – Send discarded records to an Amazon SQS queue, Amazon SNS topic, Kafka topic, or Amazon S3 bucket. For more information, see Adding a destination.

The following option is available only for DynamoDB and Kinesis event sources:

  • ParallelizationFactor – Process multiple batches from each shard concurrently.

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :uuid (required, String) —

    The identifier of the event source mapping.

  • :function_name (String) —

    The name or ARN of the Lambda function.

    Name formats

    • Function name – MyFunction.

    • Function ARN – arn:aws:lambda:us-west-2:123456789012:function:MyFunction.

    • Version or Alias ARN – arn:aws:lambda:us-west-2:123456789012:function:MyFunction:PROD.

    • Partial ARN – 123456789012:function:MyFunction.

    The length constraint applies only to the full ARN. If you specify only the function name, it's limited to 64 characters in length.

  • :enabled (Boolean) —

    When true, the event source mapping is active. When false, Lambda pauses polling and invocation.

    Default: True

  • :batch_size (Integer) —

    The maximum number of records in each batch that Lambda pulls from your stream or queue and sends to your function. Lambda passes all of the records in the batch to the function in a single call, up to the payload limit for synchronous invocation (6 MB).

    • Amazon Kinesis – Default 100. Max 10,000.

    • Amazon DynamoDB Streams – Default 100. Max 10,000.

    • Amazon Simple Queue Service – Default 10. For standard queues the max is 10,000. For FIFO queues the max is 10.

    • Amazon Managed Streaming for Apache Kafka – Default 100. Max 10,000.

    • Self-managed Apache Kafka – Default 100. Max 10,000.

    • Amazon MQ (ActiveMQ and RabbitMQ) – Default 100. Max 10,000.

    • DocumentDB – Default 100. Max 10,000.

  • :filter_criteria (Types::FilterCriteria) —

    An object that defines the filter criteria that determine whether Lambda should process an event. For more information, see Lambda event filtering.

  • :kms_key_arn (String) —

    The ARN of the Key Management Service (KMS) customer managed key that Lambda uses to encrypt your function's filter criteria. By default, Lambda does not encrypt your filter criteria object. Specify this property to encrypt data using your own customer managed key.

  • :metrics_config (Types::EventSourceMappingMetricsConfig) —

    The metrics configuration for your event source. For more information, see Event source mapping metrics.

  • :logging_config (Types::EventSourceMappingLoggingConfig) — default: Amazon MSK, and self-managed Apache Kafka only —

    The logging configuration for your event source. Use this configuration object to define the level of logs for your event source mapping.

  • :scaling_config (Types::ScalingConfig) — default: Amazon SQS only —

    The scaling configuration for the event source. For more information, see Configuring maximum concurrency for Amazon SQS event sources.

  • :maximum_batching_window_in_seconds (Integer) —

    The maximum amount of time, in seconds, that Lambda spends gathering records before invoking the function. You can configure MaximumBatchingWindowInSeconds to any value from 0 seconds to 300 seconds in increments of seconds.

    For Kinesis, DynamoDB, and Amazon SQS event sources, the default batching window is 0 seconds. For Amazon MSK, Self-managed Apache Kafka, Amazon MQ, and DocumentDB event sources, the default batching window is 500 ms. Note that because you can only change MaximumBatchingWindowInSeconds in increments of seconds, you cannot revert back to the 500 ms default batching window after you have changed it. To restore the default batching window, you must create a new event source mapping.

    Related setting: For Kinesis, DynamoDB, and Amazon SQS event sources, when you set BatchSize to a value greater than 10, you must set MaximumBatchingWindowInSeconds to at least 1.

  • :parallelization_factor (Integer) — default: Kinesis and DynamoDB Streams only —

    The number of batches to process from each shard concurrently.

  • :destination_config (Types::DestinationConfig) — default: Kinesis, DynamoDB Streams, Amazon MSK, and self-managed Apache Kafka —

    A configuration object that specifies the destination of an event after Lambda processes it.

  • :maximum_record_age_in_seconds (Integer) — default: Kinesis, DynamoDB Streams, Amazon MSK, and self-managed Apache Kafka —

    Discard records older than the specified age. The default value is infinite (-1).

  • :bisect_batch_on_function_error (Boolean) — default: Kinesis, DynamoDB Streams, Amazon MSK, and self-managed Apache Kafka —

    If the function returns an error, split the batch in two and retry.

  • :maximum_retry_attempts (Integer) — default: Kinesis, DynamoDB Streams, Amazon MSK, and self-managed Apache Kafka —

    Discard records after the specified number of retries. The default value is infinite (-1). When set to infinite (-1), failed records are retried until the record expires.

  • :tumbling_window_in_seconds (Integer) — default: Kinesis and DynamoDB Streams only —

    The duration in seconds of a processing window for DynamoDB and Kinesis Streams event sources. A value of 0 seconds indicates no tumbling window.

  • :source_access_configurations (Array<Types::SourceAccessConfiguration>) —

    An array of authentication protocols or VPC components required to secure your event source.

  • :function_response_types (Array<String>) — default: Kinesis, DynamoDB Streams, Amazon MSK, self-managed Apache Kafka, and Amazon SQS —

    A list of current response type enums applied to the event source mapping.

  • :amazon_managed_kafka_event_source_config (Types::AmazonManagedKafkaEventSourceConfig) —

    Specific configuration settings for an Amazon Managed Streaming for Apache Kafka (Amazon MSK) event source.

  • :self_managed_kafka_event_source_config (Types::SelfManagedKafkaEventSourceConfig) —

    Specific configuration settings for a self-managed Apache Kafka event source.

  • :document_db_event_source_config (Types::DocumentDBEventSourceConfig) —

    Specific configuration settings for a DocumentDB event source.

#update_function_code(params = {}) ⇒ Types::FunctionConfiguration

Updates a Lambda Event Function's code. If code signing is enabled for the function, the code package must be signed by a trusted publisher. For more information, see Configuring code signing for Lambda.

If the function's package type is Image, then you must specify the code package in ImageUri as the URI of a container image in the Amazon ECR registry.

If the function's package type is Zip, then you must specify the deployment package as a .zip file archive. Enter the Amazon S3 bucket and key of the code .zip file location. You can also provide the function code inline using the ZipFile field.

The code in the deployment package must be compatible with the target instruction set architecture of the function (x86-64 or arm64).

The function's code is locked when you publish a version. You can't modify the code of a published version, only the unpublished version.

For a function defined as a container image, Lambda resolves the image tag to an image digest. In Amazon ECR, if you update the image tag to a new image, Lambda does not automatically update the function.

Examples:

    The name or ARN of the Lambda function.

    Name formats

    • Function name – my-function.

    • Function ARN – arn:aws:lambda:us-west-2:123456789012:function:my-function.

    • Partial ARN – 123456789012:function:my-function.

    The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

  • :zip_file (String, StringIO, File) —

    The base64-encoded contents of the deployment package. Amazon Web Services SDK and CLI clients handle the encoding for you. Use only with a function defined with a .zip file archive deployment package.

    An Amazon S3 bucket in the same Amazon Web Services Region as your function. The bucket can be in a different Amazon Web Services account. Use only with a function defined with a .zip file archive deployment package.

  • :s3_key (String) —

    The Amazon S3 key of the deployment package. Use only with a function defined with a .zip file archive deployment package.

  • :s3_object_version (String) —

    For versioned objects, the version of the deployment package object to use.

  • :s3_object_storage_mode (String) —

    Specifies how the deployment package is stored. Valid values:

    • COPY (default) – Uploads a copy of your deployment package to Lambda.

    • REFERENCE – Lambda references the deployment package from the specified Amazon S3 bucket.

  • :image_uri (String) —

    URI of a container image in the Amazon ECR registry. Do not use for a function defined with a .zip file archive.

  • :architectures (Array<String>) —

    The instruction set architecture that the function supports. Enter a string array with one of the valid values (arm64 or x86_64). The default value is x86_64.

  • :publish (Boolean) —

    Set to true to publish a new version of the function after updating the code. This has the same effect as calling PublishVersion separately.

  • :publish_to (String) —

    Specifies where to publish the function version or configuration.

  • :dry_run (Boolean) —

    Set to true to validate the request parameters and access permissions without modifying the function code.

  • :revision_id (String) —

    Update the function only if the revision ID matches the ID that's specified. Use this option to avoid modifying a function that has changed since you last read it.

  • :source_kms_key_arn (String) —

    The ARN of the Key Management Service (KMS) customer managed key that's used to encrypt your function's .zip deployment package. If you don't provide a customer managed key, Lambda uses an Amazon Web Services managed key.

#update_function_configuration(params = {}) ⇒ Types::FunctionConfiguration

Modifies the version-specific settings of a Lambda Event Function.

When you update a function, Lambda provisions an instance of the function and its supporting resources. If your function connects to a VPC, this process can take a minute. During this time, you can't modify the function, but you can still invoke it. The LastUpdateStatus, LastUpdateStatusReason, and LastUpdateStatusReasonCode fields in the response from GetFunctionConfiguration indicate when the update is complete and the function is processing events with the new configuration. For more information, see Lambda function states.

These settings can vary between versions of a function and are locked when you publish a version. You can't modify the configuration of a published version, only the unpublished version.

To configure function concurrency, use PutFunctionConcurrency. To grant invoke permissions to an Amazon Web Services account or Amazon Web Services service, use AddPermission.

Examples:

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :function_name (required, String) —

    The name or ARN of the Lambda function.

    Name formats

    • Function name – my-function.

    • Function ARN – arn:aws:lambda:us-west-2:123456789012:function:my-function.

    • Partial ARN – 123456789012:function:my-function.

    The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

  • :role (String) —

    The Amazon Resource Name (ARN) of the function's execution role.

  • :handler (String) —

    The name of the method within your code that Lambda calls to run your function. Handler is required if the deployment package is a .zip file archive. The format includes the file name. It can also include namespaces and other qualifiers, depending on the runtime. For more information, see Lambda programming model.

  • :description (String) —

    A description of the function.

  • :timeout (Integer) —

    The amount of time (in seconds) that Lambda allows a function to run before stopping it. The default is 3 seconds, and the maximum allowed value is 900 seconds. For functions using Lambda Managed Instances, asynchronous invocations and event source mapping invocations (except Amazon MQ and Amazon DocumentDB) support a maximum allowed value of 5,400 seconds (90 minutes). For more information, see Lambda execution environment.

  • :memory_size (Integer) —

    The amount of memory available to the function at runtime. Increasing the function memory also increases its CPU allocation. The default value is 128 MB. The value can be any multiple of 1 MB.

  • :vpc_config (Types::VpcConfig) —

    For network connectivity to Amazon Web Services resources in a VPC, specify a list of security groups and subnets in the VPC. When you connect a function to a VPC, it can access resources and the internet only through that VPC. For more information, see Configuring a Lambda function to access resources in a VPC.

  • :environment (Types::Environment) —

    Environment variables that are accessible from function code during execution.

  • :runtime (String) —

    The identifier of the function's runtime. Runtime is required if the deployment package is a .zip file archive. Specifying a runtime results in an error if you're deploying a function using a container image.

    The following list includes deprecated runtimes. Lambda blocks creating new functions and updating existing functions shortly after each runtime is deprecated. For more information, see Runtime use after deprecation.

    For a list of all currently supported runtimes, see Supported runtimes.

  • :dead_letter_config (Types::DeadLetterConfig) —

    A dead-letter queue configuration that specifies the queue or topic where Lambda sends asynchronous events when they fail processing. For more information, see Dead-letter queues.

  • :kms_key_arn (String) —

    The ARN of the Key Management Service (KMS) customer managed key that's used to encrypt the following resources:

    • The function's environment variables.

    • The function's Lambda SnapStart snapshots.

    • When used with SourceKMSKeyArn, the unzipped version of the .zip deployment package that's used for function invocations. For more information, see Specifying a customer managed key for Lambda.

    • The optimized version of the container image that's used for function invocations. Note that this is not the same key that's used to protect your container image in the Amazon Elastic Container Registry (Amazon ECR). For more information, see Function lifecycle.

    If you don't provide a customer managed key, Lambda uses an Amazon Web Services owned key or an Amazon Web Services managed key.

  • :tracing_config (Types::TracingConfig) —

    Set Mode to Active to sample and trace a subset of incoming requests with X-Ray.

  • :revision_id (String) —

    Update the function only if the revision ID matches the ID that's specified. Use this option to avoid modifying a function that has changed since you last read it.

  • :layers (Array<String>) —

    A list of function layers to add to the function's execution environment. Specify each layer by its ARN, including the version.

  • :file_system_configs (Array<Types::FileSystemConfig>) —

    Connection settings for an Amazon EFS file system or an Amazon S3 Files file system.

  • :image_config (Types::ImageConfig) —

    Container image configuration values that override the values in the container image Docker file.

  • :ephemeral_storage (Types::EphemeralStorage) —

    The size of the function's /tmp directory in MB. The default value is 512, but can be any whole number between 512 and 10,240 MB. For more information, see Configuring ephemeral storage (console).

  • :snap_start (Types::SnapStart) —

    The function's SnapStart setting.

  • :logging_config (Types::LoggingConfig) —

    The function's Amazon CloudWatch Logs configuration settings.

  • :capacity_provider_config (Types::CapacityProviderConfig) —

    Configuration for the capacity provider that manages compute resources for Lambda functions.

  • :durable_config (Types::DurableConfig) —

    Configuration settings for durable functions, including execution timeout, retention period for execution history, and an optional ARN of the Key Management Service (KMS) customer managed key that is used to encrypt your durable execution's payload data, including input, output, and error payloads.

end

#wait_until(waiter_name, params = {}, options = {}) {|w.waiter| ... } ⇒ Boolean

Polls an API operation until a resource enters a desired state.

Basic Usage

A waiter will call an API operation until:

  • It is successful
  • It enters a terminal state
  • It makes the maximum number of attempts

In between attempts, the waiter will sleep.

# polls in a loop, sleeping between attempts
client.wait_until(waiter_name, params)

Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. You can pass configuration as the final arguments hash.

# poll for ~25 seconds
client.wait_until(waiter_name, params, {
  max_attempts: 5,
  delay: 5,
})

Callbacks

You can be notified before each polling attempt and before each delay. If you throw :success or :failure from these callbacks, it will terminate the waiter.

started_at = Time.now
client.wait_until(waiter_name, params, {

  # disable max attempts
  max_attempts: nil,

  # poll for 1 hour, instead of a number of attempts
  before_wait: -> (attempts, response) do
    throw :failure if Time.now - started_at > 3600
  end
})

Handling Errors

When a waiter is unsuccessful, it will raise an error. All of the failure errors extend from Waiters::Errors::WaiterFailed.

begin
  client.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
  # resource did not enter the desired state in time
end

Valid Waiters

The following table lists the valid waiter names, the operations they call, and the default :delay and :max_attempts values.

waiter_name params :delay :max_attempts
function_active #get_function_configuration 5 60
function_active_v2 #get_function 1 300
function_exists #get_function 1 20
function_updated #get_function_configuration 5 60
function_updated_v2 #get_function 1 300
published_version_active #get_function_configuration 5 312

Parameters:

  • waiter_name (Symbol)
  • params (Hash) (defaults to: {}) —

    ({})

  • options (Hash) (defaults to: {}) —

    ({})

Options Hash (options):

  • :max_attempts (Integer)
  • :delay (Integer)
  • :before_attempt (Proc)
  • :before_wait (Proc)

Yields:

  • (w.waiter)

Returns:

  • (Boolean) —

    Returns true if the waiter was successful.

Raises:

  • (Errors::FailureStateError) —

    Raised when the waiter terminates because the waiter has entered a state that it will not transition out of, preventing success.

  • (Errors::TooManyAttemptsError) —

    Raised when the configured maximum number of attempts have been made, and the waiter is not yet successful.

  • (Errors::UnexpectedError) —

    Raised when an error is encounted while polling for a resource that is not expected.

  • (Errors::NoSuchWaiterError) —

    Raised when you request to wait for an unknown state.
