   Thanks for the advice.
   Yes, I also just realized, Coordinator need to be replicated so it can recover from single node failure.
   But RockDB is only embedded KV store and is not replicated so only using RocksDB is not enough.
   I'll go though the Table Service doc and see how we can utilize Statelib here: https://docs.google.com/document/d/155xAwWv5IdOitHh1NVMEwCMGgB28M3FyMiQSxEpjE-Y/edit#heading=h.56rbh52koe3f.
