Isn't Intragram mostly Cassandra?

It wasn’t when I last saw it. Rocksandra ended up being a stepping stone to fbs most common distributed db, zippydb https://engineering.fb.com/2021/08/06/core-data/zippydb/

Zippydb is honestly one of the best parts of fb infra. It let you select levels of consistency vs latency

How is that different from Cassandra's Tunable consistency model?
