Memtable Flush writers doesn't actually flush in parallel
---------------------------------------------------------
Key: CASSANDRA-2178
URL: https://issues.apache.org/jira/browse/CASSANDRA-2178
Project: Cassandra
Issue Type: Bug
Reporter: Chris Goffinet
Assignee: Chris Goffinet
Priority: Minor
The flushWriter JMXEnabledThreadPoolExecutor sets the core pool min to 1, and
sets the LBQ to DatabaseDescriptor.getFlushWriters(). Increasing
memtable_flush_writers should allow us to flush more in parallel. The pool will
not grow until LBQ fills up to DatabaseDescriptor.getFlushWriters().
