Are you suggesting that we can only reuse the same FairAffinityFunction
across the logical caches within the same group? This would mean that
caches from the different groups cannot participate in JOINs or collocated
I think I like the idea, however, we need to make sure that we enforce this
restriction, at least at the SQL JOIN level.
Alexey G, Val, would be nice to hear your thoughts on this.
