stack resolved HBASE-2462. -------------------------- Resolution: Won't Fix Closing. Superceeded by other work in compaction. I opened HBASE-5627 for the outstanding simulator work. > 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 > Components: performance > Reporter: stack > Assignee: Jonathan Gray > Priority: Critical > Labels: moved_from_0_20_5 > Attachments: 2462v2.txt, standalone.txt > > > 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.
