Published new video in my recently created youtube channel about one of my favorite topics: performance.  So, here is a new video whose goal is to explain clearly what lazy evaluation is and how to use caching to boost performance.

I usually see these concepts are largely misunderstood and I think they are KEY to work with databricks from the very beginning and not to incur in performance issues. So, I decided to create these series not only to my team but to share with community while it serves to myself to remember due to my very bad long-term human memory xD. 

I hope you find it useful.

And YES, doing this with a lot of coffee...
