Tenacity support for retry logic

[jxnl]

Currently, we have a very inefficient way of handling retries. It's just a wild loop.

However, I strongly believe that we should utilize the tenacity library to improve this. One thing we could do in the future, once we've cleaned up the clients, is to support tenacity-like logic. It would be great if we could pass in:

max_retries=3

or

from tenacity import retry

create(max_retries=retry(stop=stop_after_attempt(7)), ...)

Retrying code block
Tenacity allows you to retry a code block without the need to wraps it in an isolated function. This makes it easy to isolate failing block while sharing context. The trick is to combine a for loop and a context manager.

from tenacity import Retrying, RetryError, stop_after_attempt

try:
    for attempt in Retrying(stop=stop_after_attempt(3)):
        with attempt:
            raise Exception('My code is failing!')
except RetryError:
    pass

You can configure every details of retry policy by configuring the Retrying object.

With async code you can use AsyncRetrying.

from tenacity import AsyncRetrying, RetryError, stop_after_attempt

async def function():
   try:
       async for attempt in AsyncRetrying(stop=stop_after_attempt(3)):
           with attempt:
               raise Exception('My code is failing!')
   except RetryError:
       pass
