   1. lead to pending all query before new datasource instead of old one
   2. it's more complex for graceful shutdown/refresh, 
   - close old ds to be an easy way to implement
   - pend all new query and wait existing connection release and close completely to a short time unavailable
   - keep old ds not accept new query and wait for closing completely, and the same time create a new ds to accept new query to be a better way, but it's hard to implement
