[jira] [Updated] (HBASE-14460) [Perf Regression] Merge of MVCC and SequenceId (HBASE-8763) slowed Increments, CheckAndPuts, batch operations
[ https://issues.apache.org/jira/browse/HBASE-14460?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] stack updated HBASE-14460: -- Release Note: Regression addressed narrowly on branch-1 (1.0.3+, 1.1.3+, and 1.2.0). You need to set a "hbase.increment.fast.but.narrow.consistency" and rolling restart to enable a 'fast path' for increments only (appends, checkAndPut, etc., are not address in branch-1). See the sub-task release notes for more detail. On master branch, a more substantial change is done changing write path so all check-and-put type operations -- i.e. increment, append, checkAnd*, etc. -- have the regression addressed. > [Perf Regression] Merge of MVCC and SequenceId (HBASE-8763) slowed > Increments, CheckAndPuts, batch operations > - > > Key: HBASE-14460 > URL: https://issues.apache.org/jira/browse/HBASE-14460 > Project: HBase > Issue Type: Bug > Components: Performance >Reporter: stack >Assignee: stack >Priority: Critical > Attachments: 0.94.test.patch, 0.98.test.patch, > 1.0.80.flamegraph-7932.svg, 14460.txt, 14460.v0.branch-1.0.patch, > 98.80.flamegraph-11428.svg, HBASE-14460-discussion.patch, client.test.patch, > flamegraph-13120.svg.master.singlecell.svg, flamegraph-26636.094.100.svg, > flamegraph-28066.098.singlecell.svg, flamegraph-28767.098.100.svg, > flamegraph-31647.master.100.svg, flamegraph-9466.094.singlecell.svg, > hack.flamegraph-16593.svg, hack.uncommitted.patch, m.test.patch, > region_lock.png, testincrement.094.patch, testincrement.098.patch, > testincrement.master.patch > > > As reported by 鈴木俊裕 up on the mailing list -- see "Performance degradation > between CDH5.3.1(HBase0.98.6) and CDH5.4.5(HBase1.0.0)" -- our unification of > sequenceid and MVCC slows Increments (and other ops) as the mvcc needs to > 'catch up' to our current point before we can read the last Increment value > that we need to update. > We can say that our Increment is just done wrong, we should just be writing > Increments and summing on read, but checkAndPut as well as batching > operations have the same issue.
