See #2902 for a counter proposal using a map like abstraction.

Motivation:

We're trying out a couple API's that let us add additional metadata to the endpoints provided by ServiceDiscoverer.

Modifications:

This example makes the weight metadata a first class concept on the ServiceDiscovererEvent interface.

I think there are some pros and cons

Pros:

  • It's clean.
  • It's very clear what the data is and where it comes from.

Cons:

  • Everything that needs to be passed through must become a field.
  • Right now the protocol defines three key parts: (address, status, metadata) where metadata is 'everything else'. Making meta-data first class fields muddies the waters a bit.
  • Changing the meta-data requires making a proxy class and that will rely on all underlying proxies to forward correct data, eg not use the default.
