Andrew Purtell commented on HBASE-12748: ---------------------------------------- bq. Want me to do a local perf run with it? Sure. I'm not sure we'd see a perf difference but could see an improvement in object allocation rates. Will look at this when testing the next 0.98 RC in any case. > RegionCoprocessorHost.execOperation creates too many iterator objects > --------------------------------------------------------------------- > > Key: HBASE-12748 > URL: https://issues.apache.org/jira/browse/HBASE-12748 > Project: HBase > Issue Type: Sub-task > Affects Versions: 0.94.25, 0.98.9 > Reporter: Vladimir Rodionov > Assignee: Andrew Purtell > Fix For: 2.0.0, 1.3.0, 0.98.15 > > Attachments: HBASE-12748.patch, HBASE-12748.patch, HBase-12748.patch > > > This is typical pattern of enhanced for ... loop usage in a hot code path. > For every HBase operation it instantiates iterator for coprocessor list > twice. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
