----------------------------------------------
Summary: In write heavy scenario creating in memory flushes leads
to contention
Key: HBASE-16156
URL: https://issues.apache.org/jira/browse/HBASE-16156
Project: HBase
Issue Type: Sub-task
Affects Versions: 2.0.0
Reporter: ramkrishna.s.vasudevan
Fix For: 2.0.0
In write heavy cases, the inmemory flushes blocks the write because it takes a
update lock. Dumps show that it is causing heavy contention and leads to
memstore filling up and so intern blocks the flush from happening sooner. This
JIRA is to discuss optimal settings and then make suitable changes.
