How to modify the retried function's parameter between each backoff call?

[johnib]

Hello,

I have a function that ingests records to some stream.
The stream may succeed although accepted only a strict subset of the records list.
I would like to modify the records list before it is processed again by the backoff mechanism (when using the on_predicat decorator).
In particular, I would like to filter the records that were not accepted and have them processed again.

How would I do that?

Off the top of my head, it sounds like you'd want to refactor such that the decorated function is being called with an immutable parameter that either succeeds or fails. However, I'm not sure I understand the problem as stated. Some example code might help.

I'm closing this, but please reopen if you think your use case isn't addressed. In that case, example code would be great.
