func NewHTTPPublisher(ctx context.Context, projID, topic string, src oauth2.TokenSource) (pubsub.MultiPublisher, error)

      	// Batch settings for GCP publisher
      	// See:
      	// Notes:

      	// Applications using these settings should be aware that Publish requests
      	// will block until the lowest of the thresholds in PublishSettings is met.
      	PublishSettings gpubsub.PublishSettings
      	// For subscribing
      	Subscription string `envconfig:"GCP_PUBSUB_SUBSCRIPTION"`
