Hello fellow OpenStackers, For the last while I've been looking at options for multi-region multi-master Keystone, as well as multi-master for other services I've been developing and one thing that always came up was there aren't many truly good options for a true multi-master backend. Recently I've been looking at Cockroachdb and while I haven't had the chance to do any testing I'm curious if anyone else has looked into it. It sounds like the perfect solution, and if it can be proved to be stable enough it could solve a lot of problems.
So, specifically in the realm of Keystone, since we are using sqlalchemy we already have Postgresql support, and since Cockroachdb does talk Postgres it shouldn't be too hard to back Keystone with it. At that stage you have a Keystone DB that could be multi-region, multi-master, consistent, and mostly impervious to disaster. Is that not the holy grail for a service like Keystone? Combine that with fernet tokens and suddenly Keystone becomes a service you can't really kill, and can mostly forget about. I'm welcome to being called mad, but I am curious if anyone has looked at this. I'm likely to do some tests at some stage regarding this, because I'm hoping this is the solution I've been hoping to find for quite a long time.
