# CfnEventSourceMappingPropsMixin

The `AWS::Lambda::EventSourceMapping` resource creates a mapping between an event source and an AWS Lambda function.

Lambda reads items from the event source and triggers the function.

For details about each event source type, see the following topics. In particular, each of the topics describes the required and optional parameters for the specific event source.
