----------------------------------------
we have return to much respones to drivers, not matter the schema's information
belong to the user. It may also be not safe, when some users using the same
cassandra cluster, and the user's shema information may be expose to all users.
> Cassandra driver first connection get the user's own schema information

> 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.
