I've been taking a look at this (https://github.com/stackforge/swift-ceph-backend and forks etc). Looks good.

I have some possibly dumb questions :-)

1/ Async updates

There's a comment in rados_server.py about not handling these. What exactly is the issue? (I note in Juno we need to add a policy arg, but they seem to work AFAICS).


2/ Replication

Doing some testing to 2 regions and 2 zones (each region with its own ceph cluster), I can get the ceph data out of sync between the regions if I stop one region and make changes in the other (then restart). This same test works fine for standard swift object backend. Are we in need of some more code in the replication side of things?

Cheers

Mark
