Container for the parameters to the CreateEventSourceMapping operation. Identifies a stream as an event source for a Lambda function. It can be either an Amazon Kinesis stream or an Amazon DynamoDB stream. AWS Lambda invokes the specified function when records are posted to the stream.
This association between a stream source and a Lambda function is called the event source mapping.
This event source mapping is relevant only in the AWS Lambda pull model, where AWS Lambda invokes the function. For more information, see AWS Lambda: How it Works in the AWS Lambda Developer Guide.
You provide mapping information (for example, which stream to read from and which Lambda function to invoke) in the request body.
Each event source, such as an Amazon Kinesis or a DynamoDB stream, can be associated with multiple AWS Lambda function. A given Lambda function can be associated with multiple AWS event sources.
If you are using versioning, you can specify a specific function version or an alias via the function name parameter. For more information about versioning, see AWS Lambda Function Versioning and Aliases.
This operation requires permission for the
public class CreateEventSourceMappingRequest : AmazonLambdaRequest IAmazonWebServiceRequest
The CreateEventSourceMappingRequest type exposes the following members
Gets and sets the property BatchSize.
The largest number of records that AWS Lambda will retrieve from your event source at the time of invoking your function. Your function receives an event with all the retrieved records. The default is 100 records.
Gets and sets the property Enabled.
Indicates whether AWS Lambda should begin polling the event source. By default,
Gets and sets the property EventSourceArn.
The Amazon Resource Name (ARN) of the Amazon Kinesis or the Amazon DynamoDB stream
that is the event source. Any record added to this stream could cause AWS Lambda to
invoke your Lambda function, it depends on the
Gets and sets the property FunctionName.
The Lambda function to invoke when AWS Lambda detects an event on the stream.
You can specify the function name (for example,
If you are using versioning, you can also provide a qualified function ARN (ARN that is qualified with function version or alias name as suffix). For more information about versioning, see AWS Lambda Function Versioning and Aliases
AWS Lambda also allows you to specify only the function name with the account ID qualifier
Note that the length constraint applies only to the ARN. If you specify only the function name, it is limited to 64 characters in length.
Gets and sets the property StartingPosition.
The position in the stream where AWS Lambda should start reading. Valid only for Kinesis streams. For more information, see ShardIteratorType in the Amazon Kinesis API Reference.
Gets and sets the property StartingPositionTimestamp.
The timestamp of the data record from which to start reading. Used with shard iterator type AT_TIMESTAMP. If a record with this exact timestamp does not exist, the iterator returned is for the next (later) record. If the timestamp is older than the current trim horizon, the iterator returned is for the oldest untrimmed data record (TRIM_HORIZON). Valid only for Kinesis streams.
