    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!!!!!}

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

  • @kaminipriya9835
    @kaminipriya9835 Год назад +1

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

    • @rajasdataengineering7585
      @rajasdataengineering7585  Год назад +1

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

    @suresh.suthar.24 11 месяцев назад

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

    @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.

    DataFrame is not like rdd, it is mutable

    • @rajasdataengineering7585
      @rajasdataengineering7585  25 дней назад

      No it is immutable. Better check the documentation.
