Yeah, that's a great point.

I have two separate implementations at the moment that fit both models. One is a postcode lookup service, so the address that is found absolutely needs to be returned without fail (highly available).

Another implementation has a dataset that is used in numerous different places, but can be up to 15-30 minutes old without causing any issues (eventual consistency, looser coupling).
