Hi Bryan,
For the case that the column is no timestamp and was not modified: I don't
think it will take copies of the full dataframe by assigning columns in a
loop like that. But it is still doing work (it will copy data for that
column into the array holding those data for 2D blocks), and which c

As of today there seem to be only two popular projects to have an agnostic

By filter, you mean a filter expression, or a selection vector/bitmap?

What about returning null for a null list? It looks like now the function
returns a primitive boolean, so I guess that would be a substantial change,
but null seems more correct to me.

Thanks Joris for clearing that up! It's correct that pyspark will allow the
user to do operations on the resulting DataFrame, so it doesn't sound like
I should set `split_blocks=True` in the conversion. You're right that the
unnecessary assignments can be easily avoided if not timestamps, so that

Great John, I'd be interesting to hear about progress.
Also, IMO I think we should be only focusing on encoding that have the
potential to be exploited for computational benefits (not just
compressibility). I think this is what distinguishes Arrow from other
formats like Parquet. I think this ech
