Are there existing, production ready KV stores that take advantage of CALM properties? I'm currently having to layer CALM optimizations on top of other dbs because my data model is built on associative and commutative operations but databases seem totally split between "transactional" and "eventually consistent" with seemingly no support for strong eventually consistent operations natively.
