How has index maintenance changed?
After having attended PASS Summit and seeing all the new features coming it out, it can be very easy to overlook the basics–they are boring. These features have been around forever. This may be true, but they still play an important role and ignoring them won’t help get you those fancy new features any time soon.
In this episode, our topic is index maintenance, with an emphasis on what has changed or what might change. Is the query store feature going to impact the way we maintain our indexes? We invite one our favorite guests, Sean McCown back to talk with us and give some of his thoughts.
“You can’t really change the math of re-indexing and maintenance.”
“And part of the problem is not with that, but with not having time to do maintenance is allowing business people to run the show.”
“Rebuilding an index is absolutely rebuilding the index pages and putting them in the order that they are supposed to be.”
“It’s not the stuff that they add that I think is ridiculous. It’s the stuff they don’t put in.”
