Adding no disk persistence option in zookeeper.
-----------------------------------------------
Key: ZOOKEEPER-866
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-866
Project: Zookeeper
Issue Type: New Feature
Reporter: Mahadev konar
Assignee: Mahadev konar
Fix For: 3.4.0
Its been seen that some folks would like to use zookeeper for very fine grained
locking. Also, in there use case they are fine with loosing all old zookeeper
state if they reboot zookeeper or zookeeper goes down. The use case is more of
a runtime locking wherein forgetting the state of locks is acceptable in case
of a zookeeper reboot. Not logging to disk allows high throughput on and low
latency on the writes to zookeeper. This would be a configuration option to set
(ofcourse the default would be logging to disk).
