Defines how new runs of a workflow with a particular ID may or may not be allowed. Note that it is never valid to have two actively running instances of the same workflow id.
public enum WorkflowIdReusePolicy
[OriginalName("WORKFLOW_ID_REUSE_POLICY_ALLOW_DUPLICATE")] AllowDuplicate = 1
Allow starting a workflow execution using the same workflow id.
[OriginalName("WORKFLOW_ID_REUSE_POLICY_ALLOW_DUPLICATE_FAILED_ONLY")] AllowDuplicateFailedOnly = 2
Allow starting a workflow execution using the same workflow id, only when the last execution's final state is one of [terminated, cancelled, timed out, failed].
[OriginalName("WORKFLOW_ID_REUSE_POLICY_REJECT_DUPLICATE")] RejectDuplicate = 3
Do not permit re-use of the workflow id for this workflow. Future start workflow requests could potentially change the policy, allowing re-use of the workflow id.
[OriginalName("WORKFLOW_ID_REUSE_POLICY_TERMINATE_IF_RUNNING")] TerminateIfRunning = 4
If a workflow is running using the same workflow ID, terminate it and start a new one. If no running workflow, then the behavior is the same as ALLOW_DUPLICATE
