------------------------------------------------------------
The code looks good. One question though, how do we want to document this?
I strongly suggest we add good documentation for this one.
Apache Spark do very well in doc, for example in the new "SQL" support module
the patch is accompanied with doc file [1] which makes easier to follow.
