Types

type MutableStateConsistencyPredicate 

type MutableStateConsistencyPredicate func(mutableState workflow.MutableState) bool

func HistoryEventConsistencyPredicate 

func HistoryEventConsistencyPredicate(
	eventID int64,
	eventVersion int64,
) MutableStateConsistencyPredicate

type UpdateWorkflowAction 

type UpdateWorkflowAction struct {
	Noop               bool
	CreateWorkflowTask bool
}

type UpdateWorkflowActionFunc 

type UpdateWorkflowActionFunc func(WorkflowLease) (*UpdateWorkflowAction, error)

func ResolveDuplicateWorkflowID added in v1.24.0 

func ResolveDuplicateWorkflowID(
	workflowID,
	newRunID,
	currentRunID string,
	currentState enumsspb.WorkflowExecutionState,

	currentStartRequestID string,
	wfIDReusePolicy enumspb.WorkflowIdReusePolicy,

) (UpdateWorkflowActionFunc, error)

ResolveDuplicateWorkflowID determines how to resolve a workflow ID duplication upon workflow start according to the WorkflowIdReusePolicy (for *completed* workflow) or WorkflowIdConflictPolicy (for *running* workflow).

NOTE: this function assumes the workflow id reuse policy Terminate-if-Running has been migrated to the workflow id conflict policy Terminate-Existing before it is invoked.

An action (ie "mitigate and allow"), an error (ie "deny") or neither (ie "allow") is returned.
