- onesociety2022 4y agoApple acquired FoundationDB but from what I have heard it’s not really used much. The FoundationDB founders have left Apple and are working on other things. Cassandra is the main datastore for iCloud data.
- atombender 4y agoAre you sure? The latest SIGMOD paper on FoundationDB says it's in active use. My impression is that iCloud is built on both Cassandra and FDB, and that FDB (via Record Layer in particular) is used extensively.
