Mujtaba Chohan commented on PHOENIX-2666:
-----------------------------------------
[~jamestaylor] 4x degradation is without any guidepost and table is split in 4
regions.
Even with guideposts, there is ~4x perf. degradation. Guidepost count for first
and last column is 28 and 12 respectively in this case.
> Performance regression: Aggregate query with filter on table with multiple
> column families
