It's really hard to tell if the server is queueing a lot of > compactions for the same region, lots of compactions for lots of regions, or > just falling behind. > For flushes much the same. There can be flushes in queue that aren't being > run because of delayed flushes. There's no way to know from the metrics how > many flushes are for each region, how many are delayed. Etc. > We should add either more metrics around this ( num per region, max per > region, min per region ) or add on a UI page that has the list of compactions > and flushes. > Or both. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
