Hi,
I need help with Spark SQL. I need to achieve something like the following.
If I have data like:
col_1 col_2
1 10
2 30
3 15
4 20
5 25
I need to get col_3 to be the running total of the sum of the previous rows of
col_2, e.g.
col_1 col_2 col_3
1 10 10
2 30 40
3 15 55
4 20 75
5 25 100
Is there a way to achieve this in Spark SQL or maybe with Data frame
transformations?
Thanks in advance,
