Hi Raja.. I would like to thank you for your effort in making such great videos about spark learning. your videos are make copmplex things simpler to understand. Really appreciate your effort!!
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 💪
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
