Hudson commented on HBASE-14539: -------------------------------- SUCCESS: Integrated in HBase-1.1 #693 (See [https://builds.apache.org/job/HBase-1.1/693/]) HBASE-14539 Slight improvement of StoreScanner.optimize. (larsh: rev 31ef9b3bbae67e50cceacbc8fc9529ebf228d916) * hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/StoreScanner.java > Slight improvement of StoreScanner.optimize > ------------------------------------------- > > Key: HBASE-14539 > URL: https://issues.apache.org/jira/browse/HBASE-14539 > Project: HBase > Issue Type: Sub-task > Reporter: Lars Hofhansl > Assignee: Lars Hofhansl > Priority: Minor > Fix For: 2.0.0, 1.3.0, 0.98.15, 1.2.1, 1.0.3, 1.1.3 > > Attachments: 14539-0.98.txt > > > While looking at the code I noticed that StoreScanner.optimize does not some > unnecessary work. This is a very tight loop and even just looking up a > reference can throw off the CPUs cache lines. This does safe a few percent of > performance (not a lot, though). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
