jiajunwang opened a new issue #562: AssignmentMetadataStore should skip updating if the new version is identical to the old one
URL: https://github.com/apache/helix/issues/562
 
 
   Currently, our AssignmentMetadataStore always update to ZK on any new version of assignment data. This is not necessary and increases ZK traffic.
   We should compare the new version with the in-memory cache and avoid write if updating is not necessary.
