Liang-Chi Hsieh commented on SPARK-23711:
-----------------------------------------
object hash aggregate? If you mean {{ObjectHashAggregateExec}}, seems it
doesn't support codegen and only runs interpreted mode?
For encoders, I think it is because it directly uses something like
{{GenerateUnsafeProjection}} and doesn't fallback to interpreted version for
now. Other places using this kind of codegen code path are the same too.
I didn't check window functions yet. Thanks for pointing it out.
