Ashu Pachauri commented on HBASE-16755: --------------------------------------- Picking this up. > Don't flush everything when under global memstore pressure > ---------------------------------------------------------- > > Key: HBASE-16755 > URL: https://issues.apache.org/jira/browse/HBASE-16755 > Project: HBase > Issue Type: Improvement > Components: regionserver > Reporter: Ashu Pachauri > Assignee: Ashu Pachauri > > When global memstore reaches the low water mark, we pick the best flushable > region and flush all column families for it. This is a suboptimal approach in > the sense that it leads to an unnecessarily high file creation rate and IO > amplification due to compactions. We should still try to honor the underlying > FlushPolicy. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
