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
}
