Hi Raja, Can you please cut the video duration to 15-20 mins, because if we want to repeat a video it's very difficult/time consuming. Anyways your content is really good. Keep up the good work 💪

[@rajasdataengineering7585]

Thanks for your suggestion. Sure, will cut short the video duration to 15-20 mins

[@AshokKumar-ji3cs]

No don't cut the duration your reach n every point in your explanation is really matters for us. So keep lengthy videos only.

How to connect multiple sources and load into single file

[@rajasdataengineering7585]

Create multiple dataframes connecting to different sources and combine them using union or join then write that output into single file

[@integratedfarming6631]

DataFrame is mutable, not immutable E.g: we can add new columns or modify the columns data or data types so DataFrame is mutable

[@rajasdataengineering7585]

Dataframe is immutable, not mutable. Please check the spark documentation once. When you add new column or changing the data type, it is internally creating new dataframe based on the previous one. It does not change the existing one by adding new column. API immutability is one of the basic concept of spark
