Join Selection strategy
Spark decides what algorithm will be used for joining the data in the phase of physical planning, where each node in the logical plan has to be converted to one or more operators in the physical plan using so-called strategies. The strategy responsible for planning the join is called Join Selection.

Excellent video! It would be great if you can make videos about analysis of execution plans and tuning performance for Spark. Most of youtubers focus only in very basic stuff :( Congratulations, again!

I am a fan of your work. Clear explanation and wonderful examples. Just one thing that bothers me is the continuous "right" being said. I understand it is the natural flow when you speak and in some situations it the 'r'ight' thing to say, right? 🙂. But all "right"s can be removed/trimmed from just the audio(let the video be as is). That is all I am saying 🙏. Again a fan of your work and this is the best resource for databricks!!
