I just started playing with spanner. The API is nice. Simple txs are a bit slow - seconds instead of milliseconds - ok for my use-case. I don't hear much about it though, few articles on HN, I was wondering how mature it was and how widely used it is. Is it common knowledge that it is used by a lot of orgs?

De-throne in the sense of being the top-tier multi-master consistent transactional DB. I doubt too many people use Spanner outside of Google in reality. Google would likely eventually adopt cockroackdb if it was clearly better long term.
