How to check whether my operation is fully pushed down or partially done ?
View optimized SQL is the only way to check whether the operation i am doing is fully pushed down or partially done ? i have the below in
the SAP article which says
Operations within the SELECT statement that the software can push to the
database include:
• Aggregations — Aggregate functions, typically used with a Group by statement, always produce a data set smaller than or the same size as
the original data set.
My doubt here , If i do the opearions like one query transform to just map from my source to target and another query to do the sorting and another one to group by will have a better performace or combining everything in one query transform will have a better performace ??
Thanks,
AJ.
