I expect that Sage will have a lot more to offer you in this area, but
for now I have a few responses I can offer off the top of my head. :)
1) It's early days for Ceph. We're going to be offering a public beta
of the object store Real Soon Now that I expect will give us a better
idea of how
Christian:
I've just tested this and it sure looks to me like deleting a pool
deletes the objects in it. It's not necessarily instantaneous, though
-- stuff won't get deleted until the OSD gets a new OSDMap.
Try writing something (which will generally put new maps on all the
OSDs involved) and see
Avishay:
It's been a while since we've expressly tested scalability in Ceph,
because doing so is pretty hard -- it takes a lot of nodes. The most
recent figures I'm aware of come from an early version of the code
(2007) and are described in Sage's thesis (available at
ceph.newdream.net), in which p
Hrm, it looks like csyn or some aspect of messaging was broken in the

command does) in the latest unstable version.
If you're just evaluating Ceph right now; I'd recommend doing so with
the unstable release in git, as a number of re

All,
Sage forgot to mention that of course using these modules requires a
few minor changes to Hadoop's configuration classes. If you're
comfortable editing their codebase then simply adding the ceph package
into their build system will lead you through the process (just fix
each build error!), but
