> Key: KUDU-1582
> URL: https://issues.apache.org/jira/browse/KUDU-1582
> Project: Kudu
> Issue Type: Bug
> Components: perf, tserver
> Affects Versions: 0.10.0
> Reporter: Todd Lipcon
> Assignee: Todd Lipcon
> Attachments: trace.json.gz
>
>
> On a server with ~5.5TB of data, the maintenance manager scheduler thread has
> gotten quite slow. The thread takes many tens of seconds to pick a
> maintenance operation, and then the actual operations take only a few seconds
> to run. So, the actual "duty cycle" of those threads is quite low, and
> compaction/flushing falls behind.
