Info you may already know: When you create a new collection using the Collections API, you can give it the name of an existing config with the collections.configName parameter. Changes to that config will affect all collections using it. You'll usually need to reload the collection so it re-reads the config from zookeeper. The "Tree" view does show you the entire zookeeper database from Solr's point of view. This is the common information available to every Solr server in your entire cloud. It contains information about every collection, all of your uploaded configs, and a few other things. SolrCloud still requires a fair amount of information at the core level that isn't stored in zookeeper. The index is too big, and we haven't gotten around to the rest of it. We do want to get to the point where everything relevant for a SolrCloud core (except the Lucene index) is stored in zookeeper -- for internal discussions, we call this "ZK as truth": https://issues.apache.org/jira/browse/SOLR-7269 Thanks, Shawn
