Do star-tree index aggregations span segments, or are the aggregates computed per segment?

per segment
thankyou 1
have been thinking of extending it to span multiple segments - do you have a concrete case?

Awesome, thank you. So theoretically, I should be able to make use of star-tree aggregates without a time column, and Pinot will (or could) merge the aggregates on relevant segments after partition pruning?

My use case actually is better if they are per-segment
