This looks amazing and I can't help but wonder - if the next step is
_generating the arrow batches on executors_ is it possible to reuse this to
pass data between JVM and Python UDFs? Right now, with ongoing shift towards
SQL API, this is the prominent bottleneck for Python users. An improvement
there could be a huge win.
