This association between a stream source and a Lambda function is called the event source mapping.
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 lambda:CreateEventSourceMapping
action.

public class CreateEventSourceMappingRequest : AmazonLambdaRequest IRequestEvents
The CreateEventSourceMappingRequest type exposes the following members
Name | Description | |
---|---|---|

CreateEventSourceMappingRequest() |
Name | Type | Description | |
---|---|---|---|
![]() |
BatchSize | System.Int32 |
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. |
![]() |
Enabled | System.Boolean |
Gets and sets the property Enabled.
Indicates whether AWS Lambda should begin polling the event source. By default, |
![]() |
EventSourceArn | System.String |
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 |
![]() |
FunctionName | System.String |
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
(for example, Note that the length constraint applies only to the ARN. If you specify only the function name, it is limited to 64 character in length. |
![]() |
StartingPosition | Amazon.Lambda.EventSourcePosition |
Gets and sets the property StartingPosition.
The position in the stream where AWS Lambda should start reading. For more information, go to ShardIteratorType in the Amazon Kinesis API Reference. |
