             Summary: Optionally disable File Channel fsyncs 
                 Key: FLUME-2181
                 URL: https://issues.apache.org/jira/browse/FLUME-2181
             Project: Flume
          Issue Type: Improvement
            Reporter: Hari Shreedharan
            Assignee: Hari Shreedharan


This will give File Channel performance a big boost, at the cost of possible 
data loss if a crash happens between checkpoints. 

Also we should make it configurable, with default to false. If the user does 
not mind slight inconsistencies, this feature can be explicitly enabled through 
configuration. So if it is not configured, then the behavior will be exactly as 
it is now.
