It's unlikely to be much of a performance impact since IIRC Hypertable uses pretty large files/chunks in order to minimize the metadata, and CephFS is pretty efficient about managing metadata in that scenario. Raw RADOS would be a simpler overall stack (and maybe more stable, right now) but would require implementing whatever Hypertable requires (and I think it basically wants HDFS) independently of the existing FS stuff, and that would be a non-trivial project. -Greg Software Engineer #42 @ http://inktank.com | http://ceph.com _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
