Have you considered a common backend.go method?

It feels like it could be similar to etcd, which implements the ServiceBackend interface.Is there a problem?

Can you elaborate please?

There is a backend.go file in the plugin directory that defines the ServiceBackend interface, so why don't we implement the methods in this interface? I don't know if I've made myself clear, what I'm asking is why you don't abstract into this interface form

I see. This plugin is a modified version of the Redis one which doesn't use the interface. Perhaps the interface is a newer abstraction that was introduced after the Redis plugin.
