-------------------------------------
Summary: 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
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.
