Adding additional settings to Lambda Event Sources for handling failures while processing DynamoDB and Kinesis Streams

Use Case

On Nov 25th, Lambda announced support for failure handling while processing DynamoDB and Kinesis Streams. This allows Lambda to take actions like retry limits, bisect on error etc and not retry the entire batch of records being processed. The feature announcement is here - https://aws.amazon.com/about-aws/whats-new/2019/11/aws-lambda-supports-failure-handling-features-for-kinesis-and-dynamodb-event-sources/

Currently, only batch size, starting position and max batching window are the additional parameters that are supported.

This helps in reducing the number of retries and also avoids processing duplicate entries.

Other

The Cloud Formation resource is documented here -
https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-lambda-eventsourcemapping.html

The specific additional fields that I am requesting for are:

  "BisectBatchOnFunctionError" : Boolean,
  "DestinationConfig" : DestinationConfig,
  "MaximumBatchingWindowInSeconds" : Integer,
  "MaximumRecordAgeInSeconds" : Integer,
  "MaximumRetryAttempts" : Integer,
  "ParallelizationFactor" : Integer

This is a 🚀 Feature Request
