Andrew Purtell commented on HBASE-11876: ---------------------------------------- Any chance for a quick pass over this [~lhofhansl] or [~stack]? I'd like to get this in for .6, tonight. > RegionScanner.nextRaw(...) should not update metrics > ---------------------------------------------------- > > Key: HBASE-11876 > URL: https://issues.apache.org/jira/browse/HBASE-11876 > Project: HBase > Issue Type: Bug > Affects Versions: 0.98.6 > Reporter: Lars Hofhansl > Assignee: Andrew Purtell > Fix For: 0.99.0, 2.0.0, 0.98.6 > > Attachments: HBASE-11876.patch, HBASE-11876.patch > > > I added the RegionScanner.nextRaw(...) to allow "smart" client to avoid some > of the default work that HBase is doing, such as {start|stop}RegionOperation > and synchronized(scanner) for each row. > Metrics should follow the same approach. Collecting them per row is expensive > and a caller should have the option to collect those later or to avoid > collecting them completely. > We can also save some cycles in RSRcpServices.scan(...) if we updated the > metric only once/batch instead of each row. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
