I've been trying to stay quiet and let the new-terminology issue settle, but I had a thought. Someone has already pointed out that the so-called master/slave cluster is misnamed: the so-called "master" node doesn't order the "slaves" about and indeed has no notion of being a master in any sense. It acts as a servant to the "slave" nodes, which are in charge of keeping themselves updated. So, it's kind of odd, but I could get used to calling this mode a "client/server cluster". That leaves the question of what to call Solr Cloud mode, in which no node is permanently special. I could see calling it a "herd" or suchlike. Now I'll try to shut up again. :-) -- Mark H.
