Review comment:
I actually wanted a separate config for this but I would like to do this
once we have https://issues.apache.org/jira/browse/ARROW-11059 (which I would
like to try and get in for 3.0.0).
I think changing it to half the batch size for now could make sense. I will
push that change to this PR.
