Just a thought for the future. What if we have the main process SIGTERM (or SIGUSR1) the subprocesses as a stop message and write a custom signal handler to clean up?

Yeah totally, that's long overdue. I was looking into it and should work on it sometime.

Toggle cancel_join_thread() here to avoid the queue blocking on exit.

From a clarity perspective I think it would be better to have this be a dict or object. E.g.
| request_q.put((None, query)) | |
| request_q.put(dict(query=query, req_time=None)) |
or set a field on the query dict.

Using a field in the query dict is much more elegant!

Yeah, I like the idea of making it a field in the query dict.

It doesn't but I wonder if adding a dedicated try-catch exception block in this function worth it. We currently catch all the cascade exceptions with the generic Exception class in the main function but it's probably not the cleanest way to handle the exception IMO.
Not suggesting this should be addressed in this PR but a follow-up PR to cleanup our exception handling might be good.

Any reason you replaced the word constant load type with concurrency? imo, constant sounds more closer to Constant Load which is a Continuous stream of requests.

I was thinking that constant is ambiguous, as RPS can also be constant. My other thinking is that we might later add dynamically changing RPS or dynamically changing concurrency so either RPS or concurrency could be constant or dynamic.

Do we still need this logging statement here?

No, I'll remove this thanks!

When we do a cleanup we probably should remove this file.

Yeah, this was originally added with the thought that it could be used in some test cases but we may want to remove it depending on how we decide to handle testing (unit tests, e2e tests, etc...)
