On: One million queries per second with MySQL

[hbrn]

To be fair, I skimmed through your docs and did misread them initially: I thought you don't allow foreign keys, but you actually don't allow foreign key constraints.

If you are still allowing JOINs within a shard, then I need to apologize.

And Vitess supports shard local foreign key constraints, even if Planetscale disallows them. They don't work with all the cool online ddl tech.

We do allow joins within shard.
