That's great to know, thank you. > If you have a pressing need for the feature, the mailing list archives > contain suggestions of how to change your cluster on the fly by doing a > rolling restart of your nodes with a new configuration. I've actually brought the topic up before, and have been following discussions here, so this is indeed an alternative. That said, the dynamic membership is indeed what would really help in this case. I wouldn't mind restarting the ensemble myself to add/remove nodes, but it's slightly more tricky if ZooKeeper is being provided as one of the pieces in some kind of platform.
