Compute-Storage Separation Explained

Gunnar Morling asked a great querstion on Twitter: ""Separating storage and compute" vs. "Predicate push-down" -- I can't quite square these two with each other. Is there a world where they co-exist, or is it just two opposing patterns/trends in DB tech. ?" Those are complimentary patterns and you definitely want them together. They appear contradictory because "separating storage and compute" can mean different things to different people. In this episode, I explain the various meanings of compute-storage separation, the problems it solves, the new problem it can create, and how predicate pushdown saves the day.
