---------------------------------------------------------
Here is where we call the "eval" method on each input row that the UDTF
receives:
[https://github.com/apache/spark/blob/master/python/pyspark/worker.py#L699.|https://github.com/apache/spark/blob/master/python/pyspark/worker.py#L699]
Here we can check the values of adjacent rows to see when the partition
boundary changes, in the presence of the PARTITION BY clause for TABLE input
arguments.
