Expose number of threads blocked on submitting a memtable for flush
-------------------------------------------------------------------
Key: CASSANDRA-2817
URL: https://issues.apache.org/jira/browse/CASSANDRA-2817
Project: Cassandra
Issue Type: Bug
Components: Core
Affects Versions: 0.7.0
Reporter: Sylvain Lebresne
Assignee: Sylvain Lebresne
Priority: Minor
Fix For: 0.7.7
Writes can be blocked by a thread trying to submit a memtable while the flush
queue is full. While this is the expected behavior (the goal being to prevent
OOMing), it is worth exposing when that happens so that people can monitor it
and modify settings accordingly if that happens too often.
