[jira] [Created] (ZOOKEEPER-3244) Add option to snapshot based on log size

Brian Nixon created ZOOKEEPER-3244:
--------------------------------------

             Summary: Add option to snapshot based on log size
                 Key: ZOOKEEPER-3244
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3244
             Project: ZooKeeper
          Issue Type: New Feature
          Components: server
            Reporter: Brian Nixon


Currently, ZooKeeper only takes snapshot based on the snap count. If the workload on an ensemble includes large txns then we'll end up with large amount data kept on disk, and might have a low disk space issue. 

Add a maximum limit on the total size of the log files between each snapshot. This will change the snap frequency, which means with the same snap retention number a server will eat up less disk.
