> Multi Op Watch Events
> ---------------------

> Key: ZOOKEEPER-1289
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1289
> Project: ZooKeeper
> Issue Type: New Feature
> Components: c client, java client, server
> Reporter: Marc Celani
>
> Caches built on top of zookeeper clients can become inconsistent because of
> lack of multi op watches. Our clients receive watch notifications for paths
> one at a time, and in their watch handling, invalidate the path in the cache.
> However, the cache now has an inconsistent view of zookeeper, since it is
> receiving the notifications one at a time. In general, the watch handling
> semantics do not conform with the idea of a multi op. If changes can be made
> to multiple paths atomically, all clients should be notified of that change
> atomically.
