Package io.temporal.nexus

Class WorkflowRunOperation

  • public final class WorkflowRunOperation
extends java.lang.Object
    WorkflowRunOperation can be used to map a workflow run to a Nexus operation

    Pre-release feature: Attaching multiple Nexus callers to an underlying handler Workflow:

    WorkflowOptions.getWorkflowIdConflictPolicy() is by default set to fail if a workflow is already running. That is, if a caller executes another operation that starts the same workflow, it will fail. You can set it to WorkflowIdConflictPolicy.WORKFLOW_ID_CONFLICT_POLICY_USE_EXISTING to attach the caller's callback to the existing running workflow. This way, all attached callers will be notified when the workflow completes.
