---------------------------------
Summary: maintenance manager scheduling very slow on TS with lots
of data
Key: KUDU-1583
URL: https://issues.apache.org/jira/browse/KUDU-1583
Project: Kudu
Issue Type: Bug
Components: perf, tserver
Affects Versions: 0.10.0
Reporter: Todd Lipcon
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.
