31:37 what is the answer to this questuin? It is not clear what the candidate say.
Hm v wait kr rhe bro

Can you tell me how good trendy tech submit Mittal is how deep it is. I'm willing to go through the course but I want to know how much it is
Insert INTO emp2
Select * from emp1;
select column_list
into new_table_name
from old_table
What is the answer to the last question - 'When we align transformations and action in a DAG, what is that graph called?'
Lineage graph - which specifically create the graph of RDDs or Dataframes like which RDD came from which one like that.
Insert into emp2 select * from emp1....data copy hi to karna hai select * into... Will create new table and then data copying... Tables already hai to create kyu karna
