    Atomicity of RESTful radosgw operations

    A while back we worked on radosgw doing atomic reads and writes. The first issue was making sure that two or more concurrent writers that write to the same object don’t end up with an inconsistent object. That is the “atomic PUT” issue. We also wanted to be able to make sure that when one […]
