Passing a Property Set by Reference

Subprocess methods tasked with modifying large amounts of data must copy large quantities of data as input and output arguments. This condition can negatively impact the performance and scalability of these method invocations. If you can avoid unnecessary copying of data, you can achieve improvements in performance and scalability.

Pass By Reference is a feature that allows you to avoid passing large property sets by passing just a pointer to the property sets. You can use Pass By Reference for a workflow process by using a Sub Process step. For more information, see About the Pass By Reference Feature for a Business Service.
