Use case

Manipulating the Idempotent Response Python docs
This allows to differentiate between regular and cached responses.

Java issue #1780

Solution/User Experience

You can set up a response_hook in the IdempotentConfig class to manipulate the returned data when an operation is idempotent. The hook function will be called with the current deserialized response object and the Idempotency record.
