Hello all. When, if ever, will Ceph clients have the ability to prefer certain OSDs/hosts over others?
I am running 3 replica pools across 3 data centers connected by relatively narrow links. Writes have to travel out anyway but I'd prefer to keep reads local. The thinking is that since all writes are synchronous across all replicas, it should be okay to read from a secondary that is nearer, faster or lightly loaded instead of reaching out to the primary at all times. Can this be done with a CRUSH tweak? Any ideas?
