Compactions: Use more intelligent priorities for PriorityCompactionQueue
------------------------------------------------------------------------
Key: HBASE-3160
URL: https://issues.apache.org/jira/browse/HBASE-3160
Project: HBase
Issue Type: Improvement
Reporter: Nicolas Spiegelberg
Assignee: Nicolas Spiegelberg
One of the problems with the current compaction queue is that we have a very
low granularity on the importance of the various compactions in the queue. If
a StoreFile count exceeds 15 files, only then do we bump via enum change. We
should instead look into more intelligent, granular priority metrics for
choosing the next compaction.
