An event source mapping is a Lambda resource that reads from an event source and invokes a Lambda function. You can use event source mappings to process items from a stream or queue in services that don't invoke Lambda functions directly. This page describes the services that Lambda provides event source mappings and how-to fine tune batching behavior.

Services that Lambda reads events from

Amazon DynamoDB

Amazon Kinesis

Amazon MQ

Amazon Managed Streaming for Apache Kafka (Amazon MSK)

Self-managed Apache Kafka

Amazon Simple Queue Service (Amazon SQS)
