If you're using TiKV why not use TiDB too, which is MySQL compatible?

it has nothing to do with TiDB, db9 is built from scratch.A good way to think about it is that db9 is similar to tidb-server, it provides a PostgreSQL wire protocol and SQL layer, while the actual data lives in the underlying KV layer.

If it is based on TiKV, why is it built from scratch when TiDB exists? To achieve faster boot times? I think the bigger offering here is distributed-, not serverless Postgres!

Wonder if that’s what it is, with a few changes to make it postgres wire compatible
