Context:
There are several places in the code base where we do a fetch with retry and if the request fails we do a backoff (e.g. see RetryBackoffEngineEntityFetcher). We could think about using the failsafe library:
https://github.com/jhalterman/failsafe

This would allow us to simplify the retry with backoff logic that we use in some parts of the codebase.

AT:

• everywhere we do a fetch with retry the failsafe library is used when possible.
