I need to pass some application-specific data from RelNode to Enumerator. I try to use DataContext, but it don't provide a method to add app data. So, I have to use ThreadLocal to pass app data from RelNode to Enumerator. Is it possible to add a method likes "void set(String name, Object value)" in DataContext?
