AppSyncBackedDataSource

class aws_cdk.aws_appsync.AppSyncBackedDataSource(scope, id, props, *, type, dynamo_db_config=None, event_bridge_config=None, http_config=None, lambda_config=None, open_search_service_config=None, relational_database_config=None)

Bases: AppSyncBaseDataSource

Abstract AppSync datasource implementation.

Do not use directly but use subclasses for resource backed datasources

ExampleMetadata:: infused

Example:

# api: appsync.EventApi
# ddb_data_source: appsync.AppSyncDynamoDbDataSource
# eb_data_source: appsync.AppSyncEventBridgeDataSource


# DynamoDB data source for publish handler
api.add_channel_namespace("ddb-eb-ns",
    code=appsync.Code.from_inline("/* event handler code here.*/"),
    publish_handler_config=appsync.HandlerConfig(
        data_source=ddb_data_source
    ),
    subscribe_handler_config=appsync.HandlerConfig(
        data_source=eb_data_source
    )
)

Parameters:

scope (Construct)
id (str)
props (Union[AppSyncBackedDataSourceProps, Dict[str, Any]])
type (AppSyncDataSourceType) – The type of the AppSync datasource.
dynamo_db_config (Union[IResolvable, DynamoDBConfigProperty, Dict[str, Any], None]) – Configuration for DynamoDB Datasource. Default: - No config
event_bridge_config (Union[IResolvable, EventBridgeConfigProperty, Dict[str, Any], None]) – Configuration for EventBridge Datasource. Default: - No config
http_config (Union[IResolvable, HttpConfigProperty, Dict[str, Any], None]) – Configuration for HTTP Datasource. Default: - No config
lambda_config (Union[IResolvable, LambdaConfigProperty, Dict[str, Any], None]) – Configuration for Lambda Datasource. Default: - No config
open_search_service_config (Union[IResolvable, OpenSearchServiceConfigProperty, Dict[str, Any], None]) – Configuration for OpenSearch data source. Default: - No config
relational_database_config (Union[IResolvable, RelationalDatabaseConfigProperty, Dict[str, Any], None]) – Configuration for RDS Datasource. Default: - No config

Methods

to_string()

Returns a string representation of this construct.

Return type:: str

Attributes

grant_principal: The principal of the data source to be IGrantable.

name: The name of the data source.

node: The tree node.

resource: The underlying CFN data source resource.

Static Methods

classmethod is_construct(x)

Checks if x is a construct.

Use this method instead of instanceof to properly detect Construct instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the constructs library on disk are seen as independent, completely different libraries. As a consequence, the class Construct in each copy of the constructs library is seen as a different class, and an instance of one class will not test as instanceof the other class. npm install will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the constructs library can be accidentally installed, and instanceof will behave unpredictably. It is safest to avoid using instanceof, and using this type-testing method instead.

Parameters:: x (Any) – Any object.
Return type:: bool
Returns:: true if x is an object created from a class which extends Construct.
