Very informative, thx
Great job, Sir
Wow super content
Thank You Sir
great explanation
can you post how to use iceberg in emr or using pyspark
I took your udemy course, its great. I have a doubt
I have a hive table, having parquet files with different schema(2 columns varying in data type)
when reading the data as dataframe, and writing it to another table, I am getting error:Parquet files cannot be converted
How to handle with schema data type mismatch ?
where is the next part of the video, can you drop the link ?
Where I acn find the whole video series?
Sir, please share writing spark streaming from Kafka topic and with consumer record and again sending that record to another topic
Are you going to answer rest of question on what happens to cache if table/view data modified?
It is automatically refreshed
Thank you @@ScholarNest .
How it is automatically refreshed..can you make an video on modified cache
It will bring only from memory after cache, but how spark onows if new data in source table when we are not reading the table..
Although the content is good, Too lengthy video to explain this concept
This whole concept could be covered shortly
