This is a very cool idea. It's great to the performance improvement!
Questions:
1. How does the operator process those values in each column? If the
operator needs to access all the fields, does it have additional overhead to
concat those values from different columns?
2. Do we create columns for each batch? If so, can we tune the batch size
to have even better performance?
If we can increase the batch size, then it will also affect the granularity
of pipelined execution. There seems to be a tradeoff here.
