Based on the fact that aggregations are super fast on Pinot. Does it make sense not to store these on user’s records anymore? Or it’s still better to store it on user’s records as a cache and update it whenever we hit Apache Pinot?Kishore G

as far as I can tell, Star-tree cannot help us. But what I don’t understand is that what happens if we filter the query by for example a DateTime? Smart-tree can handle it?
2- For example, we want to filter our result based on another table, we should get the IDs from that table and use external_id IN (IDs)
. If the (IDs) count gets huge, would it be a problem? By huge I mean for example 1 million or more. And if it is a problem, can Presto with join operation handle it?Kishore G
