Subject [jira] [Commented] (SOLR-5473) Split clusterstate.json per collection and watch states selectively
Date Thu, 10 Jul 2014 17:36:06 GMT

    [ https://issues.apache.org/jira/browse/SOLR-5473?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14057710#comment-14057710
] 

Mark Miller commented on SOLR-5473:
-----------------------------------

Okay, now we are getting somewhere.

So the important sum of these changes can be listed as:

* Nodes directly talk to zk when dealing with collections they don't host and do not watch
those collections in zk.
* Solrj does not update it's cached cluster state unless a request fails to a node?

How much does this complicate things for those that try and write a cloud aware client in
other languages?
