Fixing performance is predicated first on reorder of the write pipeline. Let me get that in first. It looks like that might be enough for this issue but to be proven with tooling that is yet to be written (see sibling issue of this one). See HBASE-15158 for write path reordering. Will be back here after that goes in. > Fix merge of MVCC and SequenceID performance regression > ------------------------------------------------------- > > Key: HBASE-15082 > URL: https://issues.apache.org/jira/browse/HBASE-15082 > Project: HBase > Issue Type: Sub-task > Components: Performance > Reporter: stack > Assignee: stack > Priority: Critical > Fix For: 2.0.0, 1.3.0 > > Attachments: 15082.patch, 15082v10.patch, 15082v12.patch, 15082v13.patch, 15082v14.patch, 15082v14.patch, 15082v15.patch, 15082v16.patch, 15082v2.patch, 15082v2.txt, 15082v3.txt, 15082v4.patch, 15082v5.patch, 15082v6.patch, 15082v7.patch, 15082v8.patch > > > This is general fix for increments (appends, checkAnd*) perf-regression identified in the parent issue.
