erikerlandson commented on issue #25024: [SPARK-27296][SQL] User Defined Aggregators that do not ser/de on each input row URL: https://github.com/apache/spark/pull/25024#issuecomment-509418156 With respect to the redundancy of UDAF, and UDIA, I would actually propose a deprecation path for the existing UDAF. The alternative proposed on this PR has behavior parity. It could use a story for Java, presumably something like `UDIA[AnyRef]`, or `UDIA[Object]` When using a final presentation type using a UDT, it ought to work via pyspark exactly the same as UDAF.
