Yifan Mai commented on BEAM-10641:
----------------------------------
Unfortunately combiner packing for Dataflow was rolled back in
https://github.com/apache/beam/pull/13884 because it was producing a
CombinePerKey that was a primitive and had no subtransforms, and Dataflow is
unable to execute such a CombinePerKey.
