> A new batch logging utility has been created to log batch sizing messages to
> drillbit.log. It is being used by the Parquet reader. It needs to be enhanced
> so it can be used by mid-stream operators. In particular, mid-stream
> operators have both incoming batches and outgoing batches, while Parquet only
> has outgoing batches. So the utility needs to support incoming batches.
