Summary

In this release we are happy to announce the General Availability of Idempotency utility 🚀.
The Idempotency utility provides a simple solution to convert your Lambda functions into idempotent operations which are safe to retry.
During developer preview we have taken a lot of feedback. Better documentation, support for Idempotency InProgressExpiration timestamp, register the Lambda context in your handler.

Idempotency 1.0.0 Nuget package

🌟Key features

• Prevent Lambda handler function from executing more than once on the same event payload during a time window.
• Use DynamoDB as a persistence layer for state with bring your own persistence store provider.
• Select a subset of the event as the idempotency key using JMESPath expressions.
• Payload validation to provide an additional JMESPath expression to specify which part of the event body should be validated against previous idempotent invocations.
• Set a time window in which records with the same payload should be considered duplicates
• Expires in-progress executions if the Lambda function times out halfway through

Implementation example

Here is an example on how you register the Lambda context in your handler:
