> There are a set of use cases where the Table Function can operate on a Partition row
by row or on a subset(window) of rows as it is being streamed to it.
> - Windowing has couple of use cases of this:processing of Rank functions, processing
of Window Aggregations.
> - But this is a generic concept: any analysis that operates on an Ordered partition maybe
able to operate in Streaming mode.
> This patch introduces streaming mode in PTFs and provides the mechanics to handle PTF
chains that contain both modes of PTFs.
> Subsequent patches will introduce Streaming mode for Windowing.
