As a former manager on the ops side who worked closely with the managers of the db teams, and the hadoop/hbase teams, and the presto folks, wormhole, scuba, a few other teams that may not be public knowledge, etc. I can say with absolute certainty that the only people in the company who thought it was not a sad joke that we used MySQL down in the bottom layers of the stack were the people on the db team. And why wouldn't that team like MySQL? Knowledge of its intricacies and bugs and how to work around its problems is what got them this high-paying gig. I will simply state that having also spent a long time inside FB I disagree with your assessment regarding the high regard in which you think MySQL is held within the company.

> I can say with absolute certainty that the only people in the company who thought it was not a sad joke You can say with absolute certainty that you know the opinion of thousands of engineers at Facebook? This is clearly hyperbole. It does not appear you are interested in having a meaningful discussion on this topic. > I disagree with your assessment regarding the high regard in which you think MySQL is held Where did I say it's held in high regard? I simply said there is no compelling reason to move away from it, and also said your numbers were way off base in terms of how many people are working on MySQL at FB, as well as how many people directly interact with MySQL at FB. I also greatly question how closely you were interacting with the managers of the db teams if you think there were 100 people on these teams! [EDIT: It's also possible that we just have very different definitions of people "on the db team". For people "working on MySQL" I would only include MySQL Eng, DB Client, MySQL Infra PE, and the majority of Data Performance PE. Arguably you could include some RocksDB people at this point, though their work is used in many non-MySQL ways too, and even then that brings the total to still way under 100 people. Overall I would not include teams like Wormhole or TAO as "working on MySQL", though even if you add them in, still significantly under 100.]
