Optimized Mappings

Optimized Mappings

When you develop a dynamic mapping, you might want to review the dynamic mapping and fix any issues before you run the mapping. To review the mapping, you can view an optimized mapping. An optimized mapping is a compiled version of the dynamic mapping.
To view the optimized mapping, right-click an empty area in the mapping editor and click
Show Optimized Mapping
.
The Data Integration Service generates the optimized mapping. The Data Integration Service compiles the mapping to complete the following tasks:
  • Expand dynamic ports and convert generated ports to static ports.
  • Convert dynamic complex ports to complex ports.
  • Resolve dynamic expressions.
  • Resolve parameter values to default values.
  • Link static ports.
  • Resolve run-time links to connect the ports.
The following image shows a dynamic mapping with dynamic ports, dynamic complex ports, and a mapping flow link:
The following image shows the optimized mapping in which the generated ports are converted to static ports, dynamic complex ports are converted to complex ports, and the port links are resolved:
