4.5.2.6 Using the Topology Viewer
Topology is a graphical representation and illustration of the connected entities and the dependencies between the artifacts.
The topology viewer helps you in identifying the dependencies that a selected entity has on other entities. Understanding the dependencies helps you in being cautious while deleting or undeploying an entity. Oracle Stream Analytics supports two contexts for the topology — Immediate Family and Extended Family.
You can launch the Topology viewer in any of the following ways:
-
Select the Show topology icon next to the Pipeline to launch the Topology Viewer for the selected entity.
-
Click the Show Topology icon in the Pipeline Editor.

Click the Show Topology icon at the top-right corner of the editor to open the topology viewer. By default, the topology of the entity from which you launch the Topology Viewer is displayed. The context of this topology is Immediate Family, which indicates that only the immediate dependencies and connections between the entity and other entities are shown. You can switch the context of the topology to display the full topology of the entity from which you have launched the Topology Viewer. The topology in an Extended Family context displays all the dependencies and connections in the topology in a hierarchical manner.
Note:
The entity for which the topology is shown has a grey box surrounding it in the Topology Viewer.Immediate Family
Immediate Family context displays the dependencies between the selected entity and its child or parent.
The following figure illustrates how a topology looks in the Immediate Family.

Extended Family
Extended Family context displays the dependencies between the entities in a full context, that is if an entity has a child entity and a parent entity, and the parent entity has other dependencies, all the dependencies are shown in the Full context.
The following figure illustrates how a topology looks in the Extended Family.
