Migrating Facebook to MySQL 8.0

To a first approximation, everything.

Most product engineers interact with it by querying TAO, which you can read about in various blog posts, but is basically a cache in front of MySQL (this is a vast oversimplification).

Hi, Kevin. :) As of the time I left, the bulk storage system I worked on - images, video, machine-learning datasets, backups of other things, etc. - held most of the bytes at Facebook. The MySQL/TAO complex had orders of magnitude more addressable objects, undoubtedly handled many times more requests and bytes in flight per second, but when it comes to bytes at rest they're not even number one.
