There were posts in recent weeks regarding the most stable and solid Cassandra version. I was wondering is anything better has appeared since it was last discussed. At this juncture, I don't need features, just rock solid stability. Are 0.8.* versions still acceptable, since I have experience with these, or should I take the plunge to 1+? I realize that I won't need more than 8GB RAM because I can't make Java heap too big. Is worth it still to pay money for extra RAM? Is the cache located outside of heap in recent versions? Thanks to all of you for the advice I'm receiving on this board. Best regards Maxim
