appConnector Base Activities
Control Flow Module
The Control Flow activities module provides activities for controlling flow of execution within your project.
Note that while activities such as the Parallel and Sequence schedule multiple child activities for execution simultaneously, only a single thread is used for a workflow. Each child activity of these activities executes sequentially and successive activities do not execute until previous activities either complete or go idle. As a result, these activities are most useful for applications in which several potentially blocking activities must execute in an interleaved fashion. If none of the child activities of these activities go idle, a Parallel activity executes just like a Sequence activity.
Activities
The table below shows the activities in the Control Flow activities module and their key properties.
Activity
