Implications for long-running requests about puma_worker_killer HOT 4 CLOSED

Good question. I'm looking at the source and its not clear if PWK will wait until a request finishes or it restarts it mid-flight. It appears that a request is killed mid-flight.

But I'd love someone more knowledgeable to chime in. Thank you!

PWK sends TERM immediately, it's up to puma to do the right thing and clean up correctly

That I do understand. The behavior after is defined by the somewhat-underdocumented worker_shutdown_timeout in Puma proper (and afaik once a TERM is received the worker won't be receiving new requests). However, if that timeout is set to a pretty large value, will PWK try a KILL too soon, or will it overreact and attempt more TERMs if the worker does not go away in a timely manner?

Everything we send will go through the puma interface. Right now we use term from Puma and it goes through it's paces. If we send the command multiple times to my knowledge puma doesn't have any kind of a counter or keep track of all of those "terms" and do something special if they hit some threshold.
