Subject [jira] [Created] (CASSANDRA-9533) Make batch commitlog mode easier to tune
Date Tue, 02 Jun 2015 17:04:49 GMT
Jonathan Ellis created CASSANDRA-9533:
-----------------------------------------

             Summary: Make batch commitlog mode easier to tune
                 Key: CASSANDRA-9533
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-9533
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Jonathan Ellis
            Assignee: Benedict
             Fix For: 3.x


As discussed in CASSANDRA-9504, 2.1 changed commitlog_sync_batch_window_in_ms from a maximum
time to wait between fsync to the minimum time, so one must be very careful to keep it small
enough that most writers aren't kept waiting.
