Review Comment:
The same combination of `take` of some subset of rows is basically what the
arrow filter kernel does. However curently it only accepts a single array as
input --> single array as output.
I wonder if we could implement some version of `filter` that that can be
invoked multiple times or something each time adding to the in-progress array.
