Thanks

[@AsliEngineering]

Thank you so much for this warm gesture 🙌 it really means a ton.

[@k.k.gayansanjeewa7432]

this encourage me , more dig in to these stuff too . Since it just open up the stuff and make the decision making stages very clear .

[@onkar_rajopadhye]

@AsliEngineering: Very informative which serves as a nice refresher to lexer, parser, parse tree as well as flex, bison. Thanks for that!
Couple of suggestions:
1. In a future video on this, cover parse tree in more depth.
2. Cover PG's rewrite engine and optimizer.
Thanks again!

Very Detailed video, thanks for diving in

[@AsliEngineering]

Thanks a ton!

Super informative. This got me curious about these interesting stuff again, Thanks Arpit!

[@ankurc854]

Thanks for sparking the curiosity :)

[@sparsh724]

This video was super informative, Arpit!!!

[@AsliEngineering]

Thank you Sparsh!

[@artu-hnrq]

Nice overview! Thanks for sharing

[@kritibindra4232]

This is awesome! I really love how you tell how you were able to find things like scan.l being converted to scan.c etc. It helps us in understanding how to go through the code files. Arpit, can you cover query execution plan of DBs and how can they affect performance? Or have you already covered in previous videos?

[@AsliEngineering]

That exactly was the intention :)
I have not yet covered the Query Execution Plan, but I do have plans of covering it. Thanks for the nudge.

Thanks man

[@physicsakhada592]

Deadlocks and transaction please in depth😊

[@architectingme]

Arpit, which device and software are you using to teach? It would be helpful if you share the info

[@AsliEngineering]

iPad + GoodNotes app with my custom theme.

[@SaketAnandPage]

How did you make this Red Color Pen with sparkles in Good Notes?

[@rishabhthakur2028]

I always find the compiler design the worst topic but the way you explain the things made me fall in love with the subject or topic.

[@beest_]

The build process was explained backwards.
