As Jacques says, I am working on the SQL-to-logical translator. It's best that I work single-threaded for a while, until I get the main operators (scan, filter, project, join, union, group by) implemented. That will only take a few more weeks. Then I could use some help making the translation more robust. (Note that I am not even addressing the issue of logical-to-physical translation, and query optimization, just yet.)

Two areas you could work on in the mean time. First, kick the tires of the JDBC driver. Try it in one or two common JDBC interfaces. I'd like people to be able to connect to Drill via JDBC and have it work with a minimum of headaches.

Second, You could add a test data set and some test queries. Right now we just have donuts.json. We could use, say, an employees.json and a departments.json, and a dozen or so queries that show off the key relational operations.
