If they have got, it processes its respective bytes, removes them from your buffer and writes its output to some variable that’s used by the following processing stage.
If you’re having requests from consumers that initiate CPU bound work, think about the concurrent.futures module. It incorporates The category ProcessPoolExecutor, which works by using a pool of processes to execute phone calls asynchronously.
For these kind of difficulties, additional resources are crucial. Beneath undoubtedly are a couple instruments and utilities Which may enable or not less than present some clues.
