> For testing the distributed TopN query, my entry point was banyand/dquery/topn.go. However, at this entry point, there was no pushdown. Aggregation is carried out solely on the liaison node. Each data node sends back its pre-aggregation list, and the liaison node completes the final aggregation. This aggregation process happens during the write phase on each data node, not during querying. That's the reason why there is no push-down. -- This is an automated message from the Apache Git Service.
