> Hmm, `ObjectHashAggregateExec` is used to support `TypedImperativeAggregate` which uses arbitrary JVM objects as aggregation states. I doubt that if we can make a native counterpart to it. We can't run arbitrary JVM objects, but we can provide native versions for known aggregates provided by Spark. TPC-H uses it for a `bloom_filter_agg`, for example, so we can implement an equivalent aggregate natively. -- This is an automated message from the Apache Git Service.
