- has anyone run it FB scale? for how long?

- how many experienced scylladb devops are there globally that we can hire?

Those questions asked at BigTechCo before it adopts somebody elses tech.

FB already operates RocksDb and Cassandra so there's way less technical, career, financial risk for just hacking the two together with some aggressive refactoring.

Does FB still use Cassandra? I thought they abandoned them ages ago and then databricks picked it up?

FB abandoned Cassandra (which was really only used for message inbox indexing) when they redid how messages work years ago, but the re-adopted a large C* infra when they bought Instagram.

Well, it's a separate product that Facebook acquired. True or not, it's a common perception that Facebook abandoned Cassandra.

I think it's DataStax. Databricks is the company behind Spark.
