[DISCUSS] [Design] Output Batch Sizing in Project using the RecordBatchSizer

Hi,

I have been working on a design to do Output Batch Sizing in Project using the RecordBatchSizer.
The main challenge lies in dealing with expressions that produce variable-length output columns. The following doc talks about a design for dealing with such variable-length output columns.

Please take a look and provide your comments

This work will be tracked by DRILL-6340<https://issues.apache.org/jira/browse/DRILL-6340>

Thanks

Karthik
