Sushanth Sowmyan commented on HIVE-7366:
----------------------------------------
No doc needed for this, this is strictly behind-the-scenes. :)
And yup, those look like those should be the only params needed - they gate
whether or not direct-sql will be used. I toyed with the idea of adding one
more "hive.metastore.try.direct.sql.experimental" for the newer experimental
direct sql extensions, to allow a phased introduction of these extensions but
was convinced [~ashutoshc] would get mad at me if I did. :D

> Given that get_database is easily one of the most frequent calls made on the
> metastore, we should have the ability to bypass datanucleus for that, and use
> direct SQL instead.
> This was something that I did initially as part of debugging HIVE-7368, but I
> think that given the frequency of this call, it's useful to have it in
> mainline direct sql.
