Thank you.
The shipped preview has only a bit more than 1500LOC.
The VLDB paper was presented at Rio in Aug this year already, but I'll try to come over to LA anyways :)

There are definitely some differences between the kind of UDFs that Spark supports and the kind that Froid handles. For one, Spark UDFs cannot invoke a Spark SQL query in their definition AFAIK, whereas TSQL functions can. But still, some techniques might be applicable. Definitely worth digging further!
