Could you elaborate on this a bit, or point me at some docs? I manage a 600GB db which does almost nothing but aggregates on partitioned tables - the largest of which has approx 600 million rows across all partitions. grouping in the aggregates tends to be on the partition column and rarely, if ever, would a group cross multiple partitions. We're on 9.0 and could definitely use some performance gains.
