I am pleased to announce the addition of a new QuickHit video covering the concept of cube sparsity and how it can affect calculations in a query. You'll see an example of how a simple change can have a dramatic impact on query performance, and how to monitor the number of cells being calculated.
This video runs 12 minutes and, like all our videos, can be found on the Videos tab of the site.
On a personal note, I apologize for the long gap between this and previous videos, as well as my absence from the forums. I'll be catching up on forum posts over the next week or so and plan additional videos in September.
