This post inpsired a lot of great discussion about the Spanner family of distributed databases. Someone asked about TiDB there, but there was no follow up. Can someone answer that question?

I'll pass this onto the engineering team. Thanks!

For a quick answer, I believe Daniel Abadi's followup comment addresses it:

In TiDB the pd leader is a central oracle.
