Jonathan Gray updated HBASE-3082: --------------------------------- Attachment: HBASE-3082-FINAL.patch Patch being committed. This patch is from Prakash and reviewed/approved by Ryan. I cleaned up some of the comments and lines >80 and also one minor change from patch up on RB. I'm also working on HBASE-2946 right now and changed the getLastIncrement() method to support multiple columns rather than just one. > For ICV gets, first look in MemStore before reading StoreFiles > -------------------------------------------------------------- > > Key: HBASE-3082 > URL: https://issues.apache.org/jira/browse/HBASE-3082 > Project: HBase > Issue Type: Improvement > Components: regionserver > Reporter: Jonathan Gray > Assignee: Prakash Khemani > Attachments: HBASE-3082-FINAL.patch > > > For incrementColumnValue operations, it is possible to check MemStore for the > column being incremented without sacrificing correctness. If the column is > not found in MemStore, we would then have to do a normal Get that > opens/checks all StoreFiles for the given Store. > In practice, this makes increment operations significantly faster for > recently/frequently incremented columns. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
