Optimizing Pass-Through Mappings

Optimizing Pass-Through Mappings

You can optimize performance for pass-through mappings. To pass directly from source to target without any other transformations, connect the Source Qualifier transformation directly to the target. If you use the Getting Started Wizard to create a pass-through mapping, the wizard creates an Expression transformation between the Source Qualifier transformation and the target.
