[jira] [Created] (CASSANDRA-2584) When disabling or reducing
compaction frequency, CopactionManager still shows frequent activity
When disabling or reducing compaction frequency, CopactionManager still shows frequent activity
-----------------------------------------------------------------------------------------------
Key: CASSANDRA-2584
URL: https://issues.apache.org/jira/browse/CASSANDRA-2584
Project: Cassandra
Issue Type: Improvement
Reporter: Patricio Echague
Priority: Trivial
I was playing with different set of configurations to test performance. One of those was with compaction disabled.
besides the fact that it is a bad practice to disable compaction, even when I did disable it, JConsole CompactionManager#completedTasks showed 30 tasks completed during the duration of my test.
I think it would be good to stop the tasks from being executed. It looks like the executor is still executing the tasks with NO-OP.

[jira] [Resolved] (CASSANDRA-2584) When disabling or reducing
compaction frequency, CopactionManager still shows frequent activity
Posted by "Jonathan Ellis (JIRA)" <ji...@apache.org>.

Jonathan Ellis resolved CASSANDRA-2584.
---------------------------------------
Resolution: Won't Fix
stopping / restarting the executor is a lot more work for the rest of the code base (need to deal w/ rejected execution etc).
doesn't seem like a great place to spend complexity to me.
