Feature request: Idempotency prefix is susceptible to refactoring

[leandrodamascena]

Use case

Original issue: aws-powertools/powertools-lambda-python#5897

The prefix to the Idempotency key is hardcoded to force a fully qualified name based on the location of the function that uses the decorator. There is no simple way of modifying this behavior in order to make that prefix some static value.

https://github.com/aws-powertools/powertools-lambda-dotnet/blob/develop/libraries/src/AWS.Lambda.Powertools.Idempotency/Persistence/BasePersistenceStore.cs#L59

This makes the Idempotency susceptible to future code refactoring. To prevent duplicate handling you can either

Solution/User Experience

A solution is to provide a way to override the key prefix on the makeIdempotent function. An optional argument like keyPrefix that allows a user to provided a fix string. This would allow freedom of refactoring (or even have multiple functions that are controlled by the same idempotency key space).

Considerations:

This should only control the prefix. The standard behavior of appending # would stay intact

Alternative solutions

Python implementation + documentation: https://github.com/aws-powertools/powertools-lambda-python/pull/5898

Acknowledgment

• This feature request meets Powertools for AWS Lambda (.NET) Tenets
• Should this be considered in other Powertools for AWS Lambda languages? i.e. Python, Java, and TypeScript
