Prevent parent route data reload when sub router changes

I have the following route definition:

  '/users': {
    ....
    subRoutes: {
      '/:userId': {
        ....
      }
    }

Parent route and sub route component route object:

route: {
  data () { ... }
}

Every time the sub route changes (e.g /users/1 to /users/2 ) the parent data function is called.
Is there a way to prevent the parent data function from getting called when the sub route changes?

Currently I use activate instead of data in the parent route object. But I think you should use the data function when you want to fetch data.

I have exactly the same issue.
subRoutes should not trigger parent data() if the parent doesn't change.

The point of data is that it will always be called when the route changes. If the data you are fetching is not related to the route params then using activate is correct.
