The video is nice, but in Spark 3.0 I feel Adaptive Query Execution is the best feature by miles they have introduced, any plans of making video on AQE?
Hi viresh, Beautiful explanation. Kindly explain if 1 have 1 gb file then what is minimum executor memory, cores and no of executors required to process this in spark? File is present in hdfs dir. Is there any way to calculate minimum resources. I know the calculation for maximum but i am running my jobs on shared cluster so cant go with maximum.
This is one of cool feature for biggerdata.. I think Currently this features available with Oracle DB to achieve better performance over large table partition joints.
Many thanks to you sir. 😊 i learnt spark from you
Great
You are just reading from Databricks videos, good to add queries as theory is available so many places already...
Perfect explanation.

What if the col that used in subquery is not present at FACT table. only present at DIM table ?

Can we use python libraries in Scala for ml development in Apache Spark
We can use python ML libs with Apache Spark.

I am not clear.. a broadcast join with the filter applied dimension table to the fact table, and the approach you explain are same?
Any example for this
Can you give the query for DPP in spark 3
Always best
