Were you satisfied when accessing HAWQ using ODBC? I'm looking for a more native solution (maybe based on npgsql/postgreSQL drivers) as they're usually better performance-wise. ODBC is really slow. And I even didn't get to limitations on memory size.

Hi, are you able to share details of your solution?  Did you use Kerberos or some other authentication method with ODBC?
