Description
DCP Stream request was observed to run above the slow threshold of 500ms, upto ~1.1s was observed. The command executes on worker thread, and a burst of requests starved the system of executor resources.
There's a bunch of data structures/components involved the request and these are undoubtedly under contention.
Whilst we could optimise the code and aim to remove contention/slow-down, a safe first change is to move the command to a non-blocking pattern, running on NonIO - this will free executors.
