Heuristic or hard cap to prevent fragmented commit logs from bringing down the
server
-------------------------------------------------------------------------------------
Key: CASSANDRA-2427
URL: https://issues.apache.org/jira/browse/CASSANDRA-2427
Project: Cassandra
Issue Type: Improvement
Reporter: Benjamin Coverston
Fix For: 1.0
Widely divergent write rates on column families can cause the commit log
segments to fragment. In some cases we have seen the commit log partition
overrun.
One solution here would be to create a heuristic for segment fragmentation to
trigger a flush (commit log segments/memtable) or simply track the free disk
space and force a global flush when the disk gets to 80% capacity.
