Backoff vs Tenacity

[lazarillo]

I am not trying to cause trouble, I just want to understand how backoff and tenacity differ. I came to know tenacity first.

I understand they are not exact duplicates of each other, and I am not looking for technical differences, but use-case differences.

For instance, I mostly use tenacity for communication between (micro)services. It seems to be better for that, AFAICT.

So, maybe a summary that highlights a few of the differences. Something like:

Tenacity outperforms with:

• Communication between microservices:
  • It is able to provide exponential back-off with some "jigger" to prevent overloading a service

Backoff outperforms with:

• CI/CD test suites:
  • It allows for much finer-grained control of short times, so it works better for testing whether functions complete within expected small time windows

(This is just a pretend example, I don't know that it is true. Just trying to demonstrate what I am looking for.)
