Thanks, Rajshekhar, for explaining the concept in such a simplistic way, I have a couple of paid subscriptions, and NONE of them have presented the Concept as you did … Thanks again and Finally your speed and delivery of speech are excellent, So I am not sure why other folks are complaining, Your videos series is just like a Goldmine {NOTHING LESS!!!!!}

[@ayushiagarwal528]

Could you also summarize where does DAG comes in picture after catalyst optimiser ?

[@stepup2me1]

@Raja'sDataEngineering speed of talking is way toooo fast , can you please make the recording with normal speed. I tried reducing the speed to 0.75x but it sounds like a drunken voice.

[@rajasdataengineering7585]

Sure will do

[@kaminipriya9835]

Hi SIr, Does catalyst optimizer gets implemented internally by itself or do we have to perform any manual action to initiate them?

[@rajasdataengineering7585]

Hi Kamini, it is one of the internal feature. We don't need to do anything explicitly

[@suresh.suthar.24]

Hi raza, i have a small doubt, DAG will be created after generating of Java Byte Code or before it ?
