--------------------------------------
Summary: Limit compactions per tserver
Key: ACCUMULO-4166
URL: https://issues.apache.org/jira/browse/ACCUMULO-4166
Project: Accumulo
Issue Type: Improvement
Reporter: Keith Turner
Fix For: 1.8.0
For user initiated compactions, I would like to be able to limit the number of
threads that run compactions on each tablet server. My use case is that for
Fluo tables I need to periodically compact ranges of a table to garbage collect
Fluo transactional data. However, I would like these compactions to have
minimal impact.
Being able to do the following would be nice, where the {{-m}} options is the
max number of compactions to run on any tablet server.
{noformat}
compact -t myTable -b p: -e p:~ -m 1
{noformat}
Thinking the best implementation would be to push this information to the
tablet server and let it manage, rather than having the master try to
coordinate.
