Summary

In this release we are happy to announce the first developer preview for the new Idempotency utility 🚀. The Idempotency utility provides a simple solution to convert your Lambda functions into idempotent operations which are safe to retry.

⚠️ Warning
This utility is currently in developer preview and is intended strictly for feedback and testing purposes and not for production workloads. The version and all future versions tagged with the -preview suffix should be treated as not stable. Until this utility is General Availability we may introduce significant breaking changes and improvements in response to customers feedback.

🌟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.
