Do you have an example of what purpose it would serve ? I'm asking because it's not very easy to implement with table-based algorithms, since the size of the table is determined by the GCD of all active servers' weights. Thus adding a new server will change the size of the table. It's also a feature I've never seen on other products either, which makes be doubt about its usefulness. What I'd like to implement however is the notion of spare servers, servers which are activated only above a certain load or when too many servers were lost. Maybe this is in fact what you're looking for ? > Adding new servers would also be nice, but that's likely to be a harder > project. Yes, it was already proposed but there are quite a number of structural issues. This as simple as file descriptors to check the servers, and table size for load balancing come to mind. I'd really prefer that we spend our time working on a hot reconfiguration (which will bring this benefit) than on border-line features that are supposed to work around the lack of hot reconf.
