--------------------------------------
Summary: Cassandra driver first connection get the user's own
schema information
Key: CASSANDRA-15871
URL: https://issues.apache.org/jira/browse/CASSANDRA-15871
Project: Cassandra
Issue Type: Improvement
Components: Cluster/Schema, Messaging/Client
Reporter: maxwellguo
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.
