Andrew Purtell commented on HBASE-14489: ---------------------------------------- +1 > postScannerFilterRow consumes a lot of CPU > ------------------------------------------ > > Key: HBASE-14489 > URL: https://issues.apache.org/jira/browse/HBASE-14489 > Project: HBase > Issue Type: Bug > Reporter: Lars Hofhansl > Labels: performance > Attachments: 14489-0.98.txt > > > During an unrelated test I found that when scanning a tall table with CQ only > and filtering most results at the server, 50%(!) of time is spend in > postScannerFilterRow, even though the coprocessor does nothing in that hook. > We need to find a way not to call this hook when not needed, or to question > why we have this hook at all. > I think [~ram_krish] added the hook (or maybe [~anoop.hbase]). I am also not > sure whether Phoenix uses this hook ([~giacomotaylor]?) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
