How to implement a parallel process with the ability to interrupt from within?

Question

Python

There is a function which is executed over a set of values. Gives either this value (confirmed) or None
It is necessary that, after a set of 25 confirmed values, it stops and produces a list.
Now implemented on joblib Parallel
Accordingly, a complete enumeration of all values. And after filtering None and trimming to 25.
If you do it consistently with a simple for, then it's slow.
And if joblib, then it processes only completely and also does not come out very quickly.
Is it possible somehow to do what I'm talking about or mutually exclusive paragraphs?

Answer 1

On LOR they suggested imap_unordered - it came up

Answer 2

Since there is gil in python, any object is, as it were, thread-independent. Use https://docs.python.org/3/library/collections.html... and read your validated values. Stop after 25.
