What language was Cloudflare KV Written in?

What language was Cloudflare KV written in?
I’m assuming it’s an in-house Key Value database like Redis.

My assumption is that it was written in either C++, Go, or C#. If not, it’s probably a fork of an existing database like Redis, or Aerospike.

Any help? I’ve looked everywhere.

Is this an in-memory database as well? I don’t think I could find that out anywhere.

My bet is on tokyo rust mini redis server.


https://github.com/cloudflarearchive/kyototycoon C++ but why would you care? It’s SaaS and u can’t tweak the backend/api/CF internals as a cust.
