Hello! 1. Yes, it is possible.
2. It should be somewhat faster to read from cache of smaller entities since serialization overhead is lower. 3. Can't answer on exact times. Web Console should show rebalance progress as far as my understanding goes. Not sure about CLI. 4. You can use continuous queries, event listeners or cache store for that.
