A Deeper Understanding of Spark Internals - Aaron Davidson (Databricks) 

So far the best video i watched that explains Spark execution model in high level with a good understandable example. Thanks for sharing!

Awesome training. Short, simple easy to understand and full of content. Great work

Thanks Aaron for the talk

excellent video and good job!

Nice video

Thank you so much Aaron

sound is very very low :(

He's not super-active, and doesn't respond to emails ;-)

Good video. Do you have any videos how Spark runs better or different compared to Hadoop and for which type of scenarios Spark is preferable than Hadoop.

In my spark version 2.4.3 job after all my transformations,computations and joins I am writing my final dataframe to s3 in parquet format But irrespective of my cores count my job is taking fixed amount for completing save action For distinct cores count-8,16,24 my write action timing is fixed to 8 minutes Due to this my solution is not becoming scalable How should I make my solution scalable so that my overall job execution time becomes proportional to cores used

Can you add subs to this? The auto generated ones are not good enough

its good stuff

A bit too fast at talking, but overall still understandable. Very good talk on the important concept.

This guy at the beginning. Find a seat man. Ruined it for me.

why the hell the text is written with a type writer/font?

Just shows how feeble Spark is,,,
