Toshihiro Suzuki commented on HBASE-24850: ------------------------------------------ [~ram_krish] [~anoop.hbase] It looks promising to me! How is the progress? Thanks. > CellComparator perf improvement > ------------------------------- > > Key: HBASE-24850 > URL: https://issues.apache.org/jira/browse/HBASE-24850 > Project: HBase > Issue Type: Improvement > Components: Performance, scan > Affects Versions: 2.0.0 > Reporter: Anoop Sam John > Assignee: ramkrishna.s.vasudevan > Priority: Critical > Fix For: 2.4.0 > > > We have multiple perf issues in 2.x versions compared to 1.x. Eg: > HBASE-24754, HBASE-24637. > The pattern is clear that where ever we do more and more Cell compares, there > is some degrade. In HBASE-24754, with an old KVComparator style comparator, > we see much better perf for the PutSortReducer. (Again the gain is huge > because of large number of compare ops that test is doing). This issue is to > address and optimize compares generally in CellComparatorImpl itself. -- This message was sent by Atlassian Jira (v8.3.4#803005)
