Description

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.
