I recall a couple years ago that it was rumored that Apple had bought FDB with the intention of replacing Cassandra (and I think, at the time, Apple had the largest Cassandra cluster ever known). Combined with other statements in this thread, I think that may be true. I remember reading once that iMessage used to be served by Cassandra, but now its served by FDB. This is all speculation though.

So it seems this is what happened, for CloudKit at least. [0] https://www.foundationdb.org/files/record-layer-paper.pdf https://www.foundationdb.org/files/record-layer-paper.pdf
