Lars Hofhansl created HBASE-14489: ------------------------------------- Summary: 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
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)
