Lars Hofhansl created HBASE-14539: ------------------------------------- Summary: 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
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)
