Parent Close Policy

In Go, a Parent Close Policy is set on the ParentClosePolicy field of an instance of workflow.ChildWorkflowOptions. The possible values can be obtained from the package.


The Child Workflow Options are then applied to the the instance of workflow.Context by using the WithChildOptions API, which is then passed to the ExecuteChildWorkflow() call.

import (
// ...

func YourWorkflowDefinition(ctx workflow.Context, params ParentParams) (ParentResp, error) {
// ...
childWorkflowOptions := workflow.ChildWorkflowOptions{
// ...
ctx = workflow.WithChildOptions(ctx, childWorkflowOptions)
childWorkflowFuture := workflow.ExecuteChildWorkflow(ctx, YourOtherWorkflowDefinition, ChildParams{})
// ...

func YourOtherWorkflowDefinition(ctx workflow.Context, params ChildParams) (ChildResp, error) {
// ...
return resp, nil
