Right, etcd's entire focus is on being a consensus database for distributed systems needing coordination, locking, etc. So, eventually consistent WAN replication hasn't really been a focus.
I do think this sort of cross-cluster key replication is useful and we offer it as a userspace external tool called make-mirror[1].

- tyingq 9y agoWorth noting that CockroachDB isn't using an eventually consistent model. Yes, it's not the same thing as etcd, but I can see some potential use case overlap.
- ideal0227 9y agoThere is some overlapping. But we should choose solution wisely :P. Here is a doc [https://github.com/coreos/etcd/blob/master/Documentation/learning/why.md https://github.com/coreos/etcd/blob/master/Documentation/lea...] comparing etcd with other systems, including CockroachDB. I work on etcd.
