Methods

  Name Description
Public Method AddEventSource(AddEventSourceRequest) Identifies an Amazon Kinesis stream as the event source for an AWS Lambda function. AWS Lambda invokes the specified function when records are posted to the stream.

This is the pull model, where AWS Lambda invokes the function. For more information, go to AWS LambdaL How it Works in the AWS Lambda Developer Guide.

This association between an Amazon Kinesis stream and an AWS Lambda function is called the event source mapping. You provide the configuration information (for example, which stream to read from and which AWS Lambda function to invoke) for the event source mapping in the request body.

This operation requires permission for the 

iam:PassRole
action for the IAM role. It also requires permission for the 
lambda:AddEventSource
action.
