> Project: Spark
> Issue Type: Improvement
> Components: SQL

> Reporter: Ricky Nguyen
>
> I recently saw the new JDBCRDD merged into master. Thanks for that, it works
> pretty well and is really convenient.
> It would be nice if it could have basic support for a few more types.
> * uuid (as StringType)
> * hstore (as MapType). keys and values are both strings.
> * array (as ArrayType)
> I have a patch that gets started in this direction. Not sure where or how to
> write/run tests, but I ran manual tests in spark-shell against my postgres db.
