    Some of the most common transformation that support query folding are:

    • Removing or renaming columns
    • Merging foldable queries that are based on the same source.
    • Appending foldable queries based on the same source.
    • Numeric calculations
    • Joins
    • Pivot and unpivot

    The transformations that do not support query folding include:

     

    • Merging or appending queries that are based on different sources.
      • Using some functions while adding custom columns that do not have a counterpart in SQL.
      • Adding columns with complex logic. These refer to functions that do not have equivalent functions in the data source.

    The rule of thumb that I use : is or possible to do this opération in SQL ? If yes then low chance to break m'y query folding
