Depends on the complexity and temporality of the data. SQL is all too often a golden hammer (https://en.wikipedia.org/wiki/Golden_hammer). Massively distributed message-oriented systems, such as Spine2 appears to be, can make ACID impossible (for a given level of performance, anyway).
All design is compromise. Software design is doubly so. (Apologies to Douglas Adams)
