Workflow

A workflow is a DAG that consists of phases and the relationships between phases.

A directed line segment shows the dependency between phases. The dependency decides the order of phase execution. In this example, the workflow runs from left to right after it starts. The DAG can handle the multi-branch structure as well. You can design the DAG flexibly according to the real situation. In the multi-branch situation, phases in parallel branches can run at the same time.
