Bro Thank You So much your videos helped me to get the good hike of 160% that completely changed things for me. Please create new videos. Your way of explaining things is awesome. ❤❤
bahot badhiya , i have been working in bigdata domain for last 12+ years and i can say that this is well explained. Your videos do show the effort you are putting in.
In Shuffle hash join first step is partition, For example in the code anywhere we didn't use partition, in this case also partition will happen as strategy of inside the shuffle hash join ?
I think Shuffle Sort Merge JOIN is the default join in spark from 2.3 version, right? Correct me if I am wrong. You mentioned Shuffle hash join as default join in spark.
Its a simple ex assuming that after partition ,each partion has same key matching with hashed dataset , but you should have took say 101,102 in part-1 , 102,103 in part- 2 etc
how i join small table with big table but i want to fetch all the data in small table like the small table is 100k record and large table is 1 milion record df = smalldf.join(largedf, smalldf.id==largedf.id , how = 'left_outerjoin') it makes out of memory and i cant do broadcast the small df idont know why what is best case here pls help
After watching 10000000000 videos and still not understanding this concept about joins I found yours :-) and I finally get it!
Thank you.. These words encourage me to keep creating videos like this

Since this is not sort merge join, how did sorting happen in both the tables before join?
I think Shuffle Sort Merge JOIN is the default join in spark from 2.3 version, right? Correct me if I am wrong. You mentioned Shuffle hash join as default join in spark.
From 2.3 sort merge join is default... U are right... I missed to mention suffle hash join is default till 2.3

After Shuffling same key data is in same node, then JOIN directly, why spark creates HASH???????????????????? please clear sir
Yes, after a long time
Yes, hope you like it
Can u please make a video about Spark Spill, Hive Spill
Sure, I have added it in list
@@DataSavvy Thanks
very well explained
