    Recursive Inputs are DataObjects that are used as Output and Input in the same action.

    Recursive Inputs are DataObjects that are used as Output and Input in the same action. This is usually prohibited as it creates loops in the DAG. In special cases this makes sense, i.e. when building a complex comparision/update logic.

    Usage: add DataObjects used as Output and Input as outputIds and recursiveInputIds, but not as inputIds.
