Overview

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

client = Aws::KeyspacesStreams::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.

#initialize(options) ⇒ Client

Returns a new instance of Client.

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. This can be an 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) —

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :shard_iterator (required, String) —

    The unique identifier of the shard iterator. A shard iterator specifies the position in the shard from which you want to start reading data records sequentially. You obtain this value by calling the GetShardIterator operation. Each shard iterator is valid for 15 minutes after creation.

  • :max_results (Integer) —

    The maximum number of records to return in a single GetRecords request. Default value is 1000. You can specify a limit between 1 and 1000, but the actual number returned might be less than the specified maximum if the size of the data for the returned records exceeds the internal size limit.

Returns:

#get_shard_iterator(params = {}) ⇒ Types::GetShardIteratorOutput

Returns a shard iterator that serves as a bookmark for reading data from a specific position in an Amazon Keyspaces data stream's shard. The shard iterator specifies the shard position from which to start reading data records sequentially. You can specify whether to begin reading at the latest record, the oldest record, or at a particular sequence number within the shard.

Examples:

Request syntax with placeholder values


resp = client.get_shard_iterator({
  stream_arn: "StreamArn", # required
  shard_id: "ShardId", # required
  shard_iterator_type: "TRIM_HORIZON", # required, accepts TRIM_HORIZON, LATEST, AT_SEQUENCE_NUMBER, AFTER_SEQUENCE_NUMBER
  sequence_number: "SequenceNumber",
})

Response structure


resp.shard_iterator #=> String

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :stream_arn (required, String) —

    The Amazon Resource Name (ARN) of the stream for which to get the shard iterator. The ARN uniquely identifies the stream within Amazon Keyspaces.

  • :shard_id (required, String) —

    The identifier of the shard within the stream. The shard ID uniquely identifies a subset of the stream's data records that you want to access.

  • :shard_iterator_type (required, String) —

    Determines how the shard iterator is positioned. Must be one of the following:

    • TRIM_HORIZON - Start reading at the last untrimmed record in the shard, which is the oldest data record in the shard.

    • AT_SEQUENCE_NUMBER - Start reading exactly from the specified sequence number.

    • AFTER_SEQUENCE_NUMBER - Start reading right after the specified sequence number.

    • LATEST - Start reading just after the most recent record in the shard, so that you always read the most recent data.

  • :sequence_number (String) —

    The sequence number of the data record in the shard from which to start reading. Required if ShardIteratorType is AT_SEQUENCE_NUMBER or AFTER_SEQUENCE_NUMBER. This parameter is ignored for other iterator types.

#get_stream(params = {}) ⇒ Types::GetStreamOutput

Returns detailed information about a specific data capture stream for an Amazon Keyspaces table. The information includes the stream's Amazon Resource Name (ARN), creation time, current status, retention period, shard composition, and associated table details. This operation helps you monitor and manage the configuration of your Amazon Keyspaces data streams.

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

Examples:

Parameters:

  • params (Hash) (defaults to: {}) —

    ({})

Options Hash (params):

  • :stream_arn (required, String) —

    The Amazon Resource Name (ARN) of the stream for which detailed information is requested. This uniquely identifies the specific stream you want to get information about.

  • :max_results (Integer) —

    The maximum number of shard objects to return in a single GetStream request. Default value is 100. The minimum value is 1 and the maximum value is 100.

  • :shard_filter (Types::ShardFilter) —

    Optional filter criteria to apply when retrieving shards. You can filter shards based on their state or other attributes to narrow down the results returned by the GetStream operation.

  • :next_token (String) —

    An optional pagination token provided by a previous GetStream operation. If this parameter is specified, the response includes only records beyond the token, up to the value specified by maxResults.

Returns:

#list_streams(params = {}) ⇒ Types::ListStreamsOutput

Returns a list of all data capture streams associated with your Amazon Keyspaces account or for a specific keyspace or table. The response includes information such as stream ARNs, table associations, creation timestamps, and current status. This operation helps you discover and manage all active data streams in your Amazon Keyspaces environment.

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

Options Hash (params):

  • :keyspace_name (String) —

    The name of the keyspace for which to list streams. If specified, only streams associated with tables in this keyspace are returned. If omitted, streams from all keyspaces are included in the results.

  • :table_name (String) —

    The name of the table for which to list streams. Must be used together with keyspaceName. If specified, only streams associated with this specific table are returned.

  • :max_results (Integer) —
