@tustvold I saw the conversion in RowConverter but as I understand it happens multiple times: i.e. we convert dictionary into utf8 in AggregatePartial, then cast results back to dictionary and then we do the same in AggregateFinal. Please let me know if I get your idea right: in the case of AggregatePartial followed by AggregateFinal, the schema for the first one should have Utf8 as its output and the second aggregate will then use Utf8 both as its input and as output. -- This is an automated message from the Apache Git Service.
