  1. Great video Kendra! A while back, I too used the golden hammer of index rebuilding, much to the chagrin of my storage replication out to a DR site. Talk about a waste of time and data shuffling! I’d love to see a video on statistics, covering things such as….is auto-update statistics good enough? Should we schedule an automated update for all statistics that haven’t updated frequently, etc…. Keep up the good work and thanks for the great videos you guys constantly produce!
