----------------------------------------------
bq. different users can get all the schemas information when first made a
connection
Use permissions to prevent them from being able to do that.
> 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.
