> In a non-tx cache, when the topology id is incremented, owners (both primary and backup) receiving a write command with a lower topology id throw an OutdatedTopologyException so that the originator retries the command on the new owners.
> But the originator needs to retry the command only if the owners of the key changed in any way. During a join or a leave, most of the keys should not change owners, so throwing an OutdatedTopologyException is not necessary most of the time.
