    Description

      In HoodieMergeOnReadRDD, Alexey added column prune support in PR #4888, which is nice, it can speed up MOR _rt table query significantly.

      However, this performance improvement is limited by a whitelistedPayloadClasses , so column prune is only supported in OverwriteWithLatestAvroPayload . If we implemented any other payload class, it can't utilise this feature.
