>             Project: Apache Drill
>          Issue Type: Improvement
>          Components:  Server, Client - C++, Client - Java, Client - JDBC, Client - ODBC

> JDBC and ODBC clients exposes lots of metadata regarding server version and support of
various parts of the SQL standard.
> Currently the returned information is hardcoded in both clients/drivers which means that
the infomation returned is support as of the client version, not the server version.
> Instead, a new method should be provided to the clients to query the actual server support.
Support on the client or the server should be optional (for example a client should not use
this API if the server doesn't support it and fallback to default values).
