How to set a Parent Close Policy in Go
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 go.temporal.io/api/enums/v1 package.
- PARENT_CLOSE_POLICY_ABANDON
- PARENT_CLOSE_POLICY_TERMINATE
- PARENT_CLOSE_POLICY_REQUEST_CANCEL
The Child Workflow Options are then applied to the instance of workflow.Context by using the WithChildOptions API, which is then passed to the ExecuteChildWorkflow() call.
- Type: ParentClosePolicy
- Default: PARENT_CLOSE_POLICY_ABANDON
import (
  // ...
  "go.temporal.io/api/enums/v1"
)
func YourWorkflowDefinition(ctx workflow.Context, params ParentParams) (ParentResp, error) {
  // ...
  childWorkflowOptions := workflow.ChildWorkflowOptions{
    // ...
    ParentClosePolicy: enums.PARENT_CLOSE_POLICY_ABANDON,
  }
  ctx = workflow.WithChildOptions(ctx, childWorkflowOptions)
  childWorkflowFuture := workflow.ExecuteChildWorkflow(ctx, YourOtherWorkflowDefinition, ChildParams{})
  // ...
}
func YourOtherWorkflowDefinition(ctx workflow.Context, params ChildParams) (ChildResp, error) {
  // ...
  return resp, nil
}
