Hi William,

The use case is the following, we have a datalake that is structured in 
datasets, each one of these datasets can have a set of quality measures and 
user wants to have a global measure of the dataset quality that is the average 
of all dataset quality measures. To do this what we have done is defining a 
custom measure that calculates this average, but it implies calculating again 
all quality measures and we were trying to find a way of calculating the 
average without recalculating quality measures.

Regards

hi,

Could you tell us your use case?
Normally, you can use avg function from spark sql.
Griffin support spark sql directly.

Thanks,
William
