+1 on exposing the APIs for columnar processing support.
I understand that the scope of this SPIP doesn't cover AI / ML
use-cases. But I saw a good performance gain when I converted data
from rows to columns to leverage on SIMD architectures in a POC ML
application.
With the exposed columnar proc
It would allow for the columnar processing to be extended through the
shuffle. So if I were doing say an FPGA accelerated extension it could
replace the ShuffleExechangeExec with one that can take a ColumnarBatch as
input instead of a Row. The extended version of the ShuffleExchangeExec
could then
sorry I am late to the discussion here -- the jira mentions using this
extensions for dealing with shuffles, can you explain that part? I don't
see how you would use this to change shuffle behavior at all.

I’d like to ask this vote period to be extended, I’m interested but I don’t
have the cycles to review it in detail and make an informed vote until the
25th.

My vote is 0. Since the updated SPIP focuses on ETL use cases, I don't feel
strongly about it. I would still suggest doing the following:
1. Link the POC mentioned in Q4. So people can verify the POC result.
2. List public APIs we plan to expose in Appendix A. I did a quick check.
Beside ColumnarB
It would be nice to get feedback from people who responded on the
other vote thread - Reynold, Matei, Xiangrui, does the new version
look good?
Thanks,
Tom
