@mmarkus Why is this needed exactly? The design document doesn't explain it either.

Also, what does this mean for other inner metadata usages, such as the Hot Rod view information?

I'm also slightly worried about the naming here. We're using Metadata class for user provided meta data. We should maybe try to distinguish a bit between both? Easier to do it in the inner classes than in the user-facing ones.

@galderz I've updated the JIRA with some context.

I think the hotrod topology cache can be dropped and put the topology information in this cache.

The name of the component (package + class) is "ClusterRegistry" - precisely in order to avoid confusion with the o.i.metadata

Generics defined in the interface but not used in the implementation?
