#12It's interesting to see FB migrating so much over to Oracle. 2 weeks ago was FB use of GraalVM (from Oracle). And now this. https://news.ycombinator.com/item?id=27782475
It's a stretch to claim this is a "migration". Facebook has used MySQL since its very early days — certainly since before Oracle acquired Sun and thus MySQL AB.

#13My old-man brain still can't compute this statement: "MySQL, an open source database developed by Oracle" . I know this is now factually true, but late-90s me keeps looking over my shoulder and freaking out.
Agreed. And in one sense (English is complicated) it's not true in its most obvious interpretation—that Oracle is the reason it exists. It was developed by others. Changing it to "currently being developed by Oracle." It's not that "developed by" can't mean "currently being developed by." It just isn't the most obvious meaning.

#14Only commenting to say their site makes me mad cause it breaks the browser history. I click the link, go to the fb engineering site, and the back button has no history to go back to HN. Dark Pattern UX -- gross.

Oracle has a very complete and much cheaper cloud solution relative to AWS. I've begun migrating my own projects over to their cloud. The savings on egress costs alone pays dividends.
Tying yourself to Oracle is quite a risky choice in my opinion.
After having used their non cloud products 10 years ago, I wouldn't do any business with them. At all.

#16MySQL 5.6 was released on 5 February 2013 . MySQL 8.0 was released on 19 April 2018 . >The 8.0 migration has taken a few years so far. We have converted many of our InnoDB replica sets to running entirely on 8.0. At the scale of Facebook I wonder if they are the largest MySQL user on the planet. And I take this opportunity to ask, does anyone know how does the MySQL roadmap works? What sort of features are coming or…
Youtube also use MySQL.

should read: "an open source database bought by Oracle".

Some migrations are very hard!

#19Anyone else puzzled by the shaking migration animation?
The original file has a 1920x1080 resolution. I wonder if it is related to the shaking.
Good article nevertheless.

#20I wonder what order of magnitude of rows they deal with and how they optimize indices for querying that data.
