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.

Normally, you can use avg function from spark sql. Griffin support spark sql directly.
