> We know that cassandra driver making a conenction with the coordinator node first time , the driver may select all the keyspaces/tables/columns/types from the server and cache the data locally.
> For different users they may have different tables and types ，so It is not suitable to get all the meta data cached , It is fine to just cache the user's own schema information not all.
> And doing this is safe and save first time connection resourse.
