Is there a way to pass a RecordBatch (or a batch wrapped as a Table) to
Take and get back a Table composed of in-place (zero copy) slices of the
input? I suppose this is not too hard to code, just wondered if there is
already a utility.

Hi John,
Arrays have a `Slice()` method that allows getting a zero-copy slices of
the array given an offset and a length. If you had a set of ranges it
wouldn't be too hard to write a function that creates a new chunked array
made up of these slices.
Of course, there are likely cases where the ov
Thanks for the input. This is motivated by use-cases where suboptimal
compute is Ok in order to preserve a lower memory profile. I wanted to be
sure I wasn't overlooking a utility before I write my own.
