    Hey Brent, great video, do you have any recommendations on training for developers to learn techniques like queuing inserts? Is queuing of inserts something I’d need to build on my own or does sql have this ability built in? I’ve tried googling this technique but I don’t seem to be finding anything related. Thanks!

    • @TheBrentOzar

      Not sure what you mean by queueing inserts - if you send a command to a database, it's executed immediately.

      @@TheBrentOzar around 34:50 (ish) you mentioned queuing up the view count updates, this sounds like a great idea and I was curious if it’s an ability SQL supports or if the developers had to engineer their own work around for it. Also any recommendations you have on training to cover understanding performance issues like this would be greatly appreciated. I’ve recently come into a project with… let’s just say lots of room for changes to increase efficiency - in both the database dev and web dev side. Current team says it’s because the server doesn’t have enough power but I’m thinking there’s probably a lot to be done on our side (dev) to make it better.

      @@TheFunVampire the developers had to do it. Nothing's built into the product for that.

      @@TheBrentOzar ah bummer. It sounds like a great idea and sounds like something a lot of people would run into. My guys here are running a function making 6 or more (depending on whats going on, could be 30-50) inserts to different tables at the load of every page. We get 100+ pages loading every second, guess i need to figure out a way to queue those up and start looking for more red flags. Thanks much for the input.
