-------------------------------------
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]?)
