DataFlow Application Life Cycle
Composing and executing an application has a life cycle with the followiong phases:
1. Creating a LogicalGraph that contains the composition and execution of DataFlow applications.
2. Constructing operators by adding them to the LogicalGraph.
3. Setting properties on operators as required.
4. Connecting the ports of the operator.
5. Compiling the LogicalGraph and optionally setting engine configuration settings.
6. Executing the LogicalGraph.
7. (Optional) Monitoring the progress of the executing graph.
Details for Steps 1 to 4 are available in
Composing an Application. You can compose an application by using the operators to meet the specified requirements. For more information about the available operators, see
DataFlow Operator Library.
You can modify the properties to manage the composition or run time behavior of the operator.
Detailed information for Step 5 is available in
Compiling an Application.
Detailed information for Steps 6 and 7 are available in
Executing an Application.
