Weird, did they try to use https://www.scylladb.com/ ?
- 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.

- 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.

When you already know Cassandra, and you already know RocksDB, and you already have an engineering team, it makes far more sense to combine the two things you know how to use at scale than to try to use some new thing NOBODY has run at scale.

I was going to say the same thing. It seems pretty clear at this point that Java is not a good programming language to build a database on if you care about strong 99% latency guarantees. The engineers in the article came to this conclusion and so did the Scylla people years ago. Scylla is AGPL for the OSS version though so testing it out would not be an option without getting a commercial license first.
Doesn't AGPL allow commercial use?

They can't test on production servers. Fake data, non-userfacing servers, sure.
Even if that is a problem, we provide anyone that is interested with a 30-day evaluation license of Scylla Enterprise.
If I'm trying a products evaluation license, you can be sure I've tried literally every other option under the sun first, including investigating the possibility rolling my own if situationally appropriate. No form of development is slower than the kind where I have to wait for a company in another timezone to give me permission to use their software, so it's always last on my options list unless the company has frankly amazing reviews that pique my curiosity.

Noone claims that a product using the MySql driver is a derivative work of the MySql server?
Edit: Of course, IANAL...
