Apparently ZooKeeper 3.5 implements the removal of Watchers[1] (thanks Ilan for this FYI). It seems helpful for SolrCloud to remove watchers that are no longer pertinent. This isn't an area I'm familiar with. I see that the Curator framework supports it too. Has anyone else looked into using this? For example to manage state.json watchers. Granted for that one, you may need a local ref-count, probably. Or use one Watcher per replica; not sure if that's a scale concern. Also curious if others have considered what it would look like for Curator to manage watching collection states -- like what utilities Curator has that would be well suited.
