The figure above shows the Runtime pattern for this Multi Step Gather variation, specifically aimed at gathering changes in a structured data source.

In this instance, the main Population pathway (Gather 2, Process, and Apply) handles both the initial load and the update of the target Data Server.

  • For the initial load, Gather 2 obtains the data from the source directly.
  • For update, however, a separate step is required (Gather 1), which reads the changes from the source and passes them to the main pathway.


Using the same main pathway for both initial load and updates is an important feature to help maintain data consistency and integrity.

The figure above allows for the possibility that some of the nodes may be combined—Process and Apply nodes in this case.

For examples of runtimes for unstructured data, please refer to the redbook: Patterns: Portal Search Custom Design, SG24-6881.
