      In this mode SolrJ would not watch any ZK node

      It fetches the state on demand and cache the most recently used n collections in memory.

      SolrJ would not listen to any ZK node. When a request comes for a collection ‘xcoll’
      it would first check if such a collection exists
      If yes it first looks up the details in the local cache for that collection
      If not found in cache , it fetches the node /collections/xcoll/state.json and caches the information
      Any query/update will be sent with extra query param specifying the collection name , version (example _stateVer=xcoll:34) . A node would throw an error (INVALID_NODE) if it does not have the right version
      If SolrJ gets INVALID_NODE error it would invalidate the cache and fetch fresh state information for that collection (and caches it again)

      If there is a connection timeout, SolrJ assumes the node is down and re-fetch the state for the collection and try again
