------------------------------------------
Summary: Add l4w command "snap" to trigger log rotation and
snapshotting
Key: ZOOKEEPER-1729
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1729
Project: ZooKeeper
Issue Type: Improvement
Components: server
Reporter: Thawan Kooburat
Assignee: Thawan Kooburat
Priority: Minor
"snap" command can be used to trigger log rotate and snapshotting on each
server.
One use case for this command is to make server restart faster by issuing snap
command before restarting the server. This help when txnlog is large (due to
txn size or number of txn)
snap is a blocking command, it will return when snapshot is written to disk. So
it is safe to call this prior to restarting the server.
