Yes, but I understand they use Cassandra heavily https://www.techrepublic.com/article/apples-secret-nosql-sauce-includes-a-hefty-dose-of-cassandra/ https://www.techrepublic.com/article/apples-secret-nosql-sau...), and I was curious about why they use FoundationDB in some settings vs Cassandra in others.
