Hi guys, quick question about the behavior of aggregations in Pinot: in the case of

SUM()

, is it done in the Server, Broker or both? If I run queries with lots of SUMs going on, should I expect the heavier work to be done by the Server or the Broker?

Server does the heavy lifiting by performing the query on data it hosts. Broker takes the result of the servers and does a final merge.

Ah, cool, good to know, thanks! 🙂
