Subject [jira] [Created] (HBASE-9528) Adaptive compaction
Date Fri, 13 Sep 2013 03:42:53 GMT
Liang Xie created HBASE-9528:
--------------------------------

             Summary: Adaptive compaction
                 Key: HBASE-9528
                 URL: https://issues.apache.org/jira/browse/HBASE-9528
             Project: HBase
          Issue Type: Brainstorming
    Affects Versions: 0.98.0
            Reporter: Liang Xie


Currently, the compaction policy granularity is based on single machine. we had a thought
that introduce a new cluster granularity decision, such that we could improve those case per
cluster running status:
1) many nodes are compacting aggressive, we call it cluster compaction storm, we should throttle
it.
2) do more compaction if low traffic in current cluster(similar with off-peak feature), not
limit by config timerange(like off-peak timerange), just trigger by load or qps or other stuff.

comments? thanks
