> All that big facebook and apple data is happening in cassandra (and foundationdb for apple)

Not sure about Instagram, but I can tell you with complete confidence that Facebook proper (meaning specifically Facebook, not the rest of Meta) moved away from Cassandra well over a decade ago. They originally used Cassandra for FB messages / Messenger, but soon migrated to HBase and then over to MySQL / MyRocks.

That is not at all surprising. We all know they have the resources to find a solution to their massive data problems.

yep and the solution is sharded MySQL

Not MySQL Raft? I am desperate to see the source.
