Hello Does RADOS support metadata queries? I have gone through librados and the "rados" command line tool, and there doesn't seem to be a way for me to say, query the object store saying: "Give me all objects with Xattr Video = 1". The only way I can think of is to write some of my own code using librados. Any pointers if the system has a metadata service or something that I can query? (I have seen few diagrams showing a metadata cluster as part of Ceph which supports metadata operations, how can I leverage that? reference diagram: http://www.usenix.org/event/osdi06/tech/full_papers/weil/weil_html/fig/overview.png) Regards Atish -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
