Deneche A. Hakim commented on DRILL-1908:
-----------------------------------------
Also, when a partition of rows exceeds the current processed batch, it will be
kept as "pending" and processed when the WindowFrameRecordBatch.next() is
called again. If the schema changes, the framer is "rebuilt" and the pending
information is lost which may lead to incorrect results. This can be fixed, but
I will first need to generate some test data that generate this kind of
problems.
