But I'd like to keep independency of path-selector from the type of I/O structure as much as possible, since both bio-based targets and request-based targets may want to use the same path-selector in the future. (e.g. multipath, which is requset-based, and mirror, which is bio-based.) So if we need only a few arguments, non-structured parameters would be good, I think. Do you have any idea what other parameters in BIO are useful for load balancing decision?
