Re: Expand the Spark SQL programming guide?
The examples look great indeed. Seems a good addition to the existing documentation. I understand the UDAF examples don't apply to Python but is there any relevant reason to skip Python API altogether from this window functions documentation?

Hi Anton,
Your example and documentation looks great! I left some comments
suggesting a few additions, but the PR in its current state is a great
improvement!
Thanks,

I think it will make sense to show a sample implementation of
UserDefinedAggregateFunction for DataFrames, and an example
of the Aggregator API for typed Datasets.
Jim, what if I submit a PR and you join the review process? I
also do not mind to split this if you want, but it seems to
