Summary
This release adds a change to the idempotency utility, expiring in-progress executions if the Lambda function times out halfway through.
The new feature requires no code changes. However, if you're using just the idempotent_function decorator, you will want to register the Lambda context on your handler to take advantage of this feature:
To prevent against extended failed retries when a Lambda function times out, Powertools now calculates and includes the remaining invocation available time as part of the idempotency record. If a second invocation happens after this timestamp, and the record is marked as INPROGRESS, we will execute the invocation again as if it was in the EXPIRED state (e.g, expire_seconds field elapsed).
We also enabled static analysis (mypy) on the new statically typed documentation snippets - big thanks to @VictorCovalski for spotting one issue in Event Handler that later led to 50 other fixes.
Oh! Did I also tell you we’ve got a new full time maintainer? Big welcome to Ruben 😉 https://twitter.com/rubenfonseca
