I had a few more basic Swift questions..
1. In Swift, when a rebalance is happening, does the client have write access to the object? Does Swift have a mechanism to lock down one copy which it is moving, and allow updates to the remaining two copies and do a final sync somehow? What is the mechanism?
2. I did see that Swift has a configurable number of replicas. Can it be set to 1? If it is set to 1, how does it work for the question above w.r.t rebalance? I do understand a single replica does not make sense, I did want to understand what it does in that case though.
3. If one of the nodes returns an error during a PUT(say, disk full), the request is sent to the handoff node, but how is the handoff node configured in the ring? Is it a special entry, or is it picked based on some algorithm or something else?
