Connecting workflows with artifact event triggers#
In the following example, we define an upstream workflow and a downstream workflow, and define a trigger in a launch plan to connect the two workflows via an artifact event.
Imports#
First we import the required packages:
Upstream artifact and workflow definition#
Then we define an upstream artifact and a workflow that emits a new version of UpstreamArtifact when executed:
Artifact event definition#
Next we define the artifact event that will link the upstream and downstream workflows together:
Downstream workflow definition#
Then we define the downstream task and workflow that will be triggered when the upstream artifact is created:
Launch plan with trigger definition#
Finally we create a launch plan with a trigger set to an OnArtifact object to link the two workflows via the Upstream artifact. The trigger will initiate an execution of the downstream downstream_wf workflow upon the creation of a new version of the Upstream artifact.
Note
The OnArtifact object must be attached to a launch plan in order for the launch plan to be triggered by the creation of a new version of the artifact.
