[GitHub] [helix] Jackie-Jiang opened a new issue #331: CallbackHandler async re-subscribe watcher can potentially miss events

Jackie-Jiang opened a new issue #331: CallbackHandler async re-subscribe watcher can potentially miss events
URL: https://github.com/apache/helix/issues/331
 
 
   In CallbackHandler, the re-subscription of the watcher for CALLBACK happens asynchronously. If the re-subscription happens after the change of the path, then we will miss the change until the next change happens.
