Data Source stage with stream output link

A database query whose results are returned on an output link is started only one time, when the job instance is started. It is not restarted during every service call request.

Note: This design feature of an IBM® InfoSphere® DataStage® job is applicable for Topology III (jobs with ISD Input and ISD Output stages).

To extract data from a data source, use a reference link to perform the lookup.
