Re: Resurrect FairAffinityFunction

Dima, It is not hard to implement. It is hard to reason on whether your query will fail or not. Moreover, cache groups is an antipattern for SQL, personally I do not want users to use it unless absolutely needed (large topologies, large number of caches). Also take in count that the same problem

Re: Resurrect FairAffinityFunction

Vladimir, I would let other guys confirm, but I believe the reason is that if it recalculates distribution every time from scratch, it would trigger too much redundant data movement during rebalancing. Fair function not only tries to provide best possible distribution, but also minimizes this
