[jira] [Commented] (ZOOKEEPER-1721) Ability to run without writing to disk

    [ https://issues.apache.org/jira/browse/ZOOKEEPER-1721?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13703403#comment-13703403 ] 

Raul Gutierrez Segales commented on ZOOKEEPER-1721:
---------------------------------------------------

In Linux this is as easy as setting dataDir and dataLogDir to somewhere inside /dev/shm (possibly other platforms support something similar). Not sure it's worth supporting this with code as it might unnecessarily complicate other sections.

> I use zookeeper for cluster synchronization. We have no need for keeping persistent state across zookeeper restarts. For performance enhancement would be good to have possibility to run without writing snapshots and logs.
