The challenge here is that the intermediate result (e.g. `list` for `percentile`) must be of the same type of the input. In order to support any aggregation function, we need to figure out a way to store the intermediate result as a separate column (similar to star-tree). The query engine needs to smartly choose the intermediate result column to aggregate on. We also need to decide what value to put in the original column (or not allow querying it directly). -- This is an automated message from the Apache Git Service.
