Facebook/meta uses mySQL, but with a completely different engine (myrocks) and sharding techniques. YouTube uses mySQL but they've also rewritten major portions for scalability. (Vitess) Just because a company is using a technology you've heard of doesn't mean it's what you expect.

YouTube uses Spanner now, they migrated off Vitess a while ago

  Can you share why they migrated? Vitess seemed to be working for them for a long time.

    When Vitess was donated to CNCF, there was an internal push from within Google to migrate everything to Spanner. I do not know any other reason. Disclaimer: Vitess Maintainer
