ha I was right, the job in queue never finish for some reason. Now I have to figure out why. queue-warehouse finish jobs and wait for new jobs, so this is not deadlock. But I have to figure out why the hell queue job freeze during the process.

How would you solve this? How to figure out on which line the app freeze during the process… I can add debugs everywhere, but it can take a lot of time to guess.

@kwladyka Add timeouts. Generate alert when timeout occurs. https://clojurians.slack.com/archives/C05423W6H/p1582884256187100

And the cli itself of course: https://lambdaisland.com/blog/2019-12-15-advent-of-parens-15-jcmd-and-jstack

Is there an actual difference between pipeline and pipeline-blocking? In the source, both functions call out to pipeline* - the first passes :compute as the "type" argument, and the second passes :blocking But it looks like both of those conditions fall into the same case https://github.com/clojure/core.async/blob/1c5efa72ebf65cd23315311d2bc3d890b780696e/src/main/clojure/clojure/core/async.clj#L520

currently, no

conceptually, use pipeline for cpu-only tasks, use pipeline-blocking if your task has i/o or other blocking ops

and then we won't break you if we change the executor implementation in the future

Fair enough, thank you!

pipeline could potentially used its own fixed size pool in the future
