stack commented on HBASE-2462: ------------------------------ @Nicolas Good stuff. Shall we commit this (after making sure it doesn't break metrics patch?) then work on algorithm implementation in another issue? > Review compaction heuristic and move compaction code out so standalone and > independently testable > ------------------------------------------------------------------------------------------------- > > Key: HBASE-2462 > URL: https://issues.apache.org/jira/browse/HBASE-2462 > Project: HBase > Issue Type: Improvement > Reporter: stack > Assignee: Jonathan Gray > Priority: Critical > > Anything that improves our i/o profile makes hbase run smoother. Over in > HBASE-2457, good work has been done already describing the tension between > minimizing compactions versus minimizing count of store files. This issue is > about following on from what has been done in 2457 but also, breaking the > hard-to-read compaction code out of Store.java out to a standalone class that > can be the easier tested (and easily analyzed for its performance > characteristics). > If possible, in the refactor, we'd allow specification of alternate merge > sort implementations. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
