I did the TC14 Extreme Data Blending session...Tableau has switched up their video providers multiple times over the years, hopefully they will stick with YouTube. Anyways, I did a slightly shorter version of that presentation as a Think Data Thursday, here's the link:
Cool - thank you for that Jonathan!
With a move to YouTube, it would be great if a link to download the worksheets were also included.
I assume that the links on the "Official" training videos are being checked
Excellent presentation on blending, by the way!
