Thank you for organizing and recording these videos @MarqueeCrew! Always a pleasure to hear from fellow enthusiasts and learn from their experience. These bite-sized video series are a great medium.
My journey like most folks transitioning into Alteryx was mostly about trial and error learning. I was a master at building what I describe as dreadful pieces of art. Solutions worked but there was a lot to be desired from a performance standpoint. I got judged all the time but in hindsight needed that to get my act together. I probably have gotten better at building efficient solutions, and can definitely sound more intelligent than before, but still have areas of improvement.
It is a very broad yet deep topic, but if folks are comfortable, I would love to hear everyone's thoughts on aspects they focus on while tuning, maybe approaches & tips. I am mostly self-taught in Alteryx and often feel the need to share and learn from others. E.g. the approach in this video was new to me: https://www.youtube.com/watch?v=tHrqmbgfK4Q
Yes, I definitely tune my workflow to run as fast as possible. Usually I just build it so it works first, then gradually improve each tool and process within it to speed it up. Usually I get good improvements through data cleansing and attention to sorts and joins. I have also done some work to determine the best memory allocations for various workloads. To my surprise, more memory wasn't always better.
