Roadmap

CockroachDB is currently in beta. We track issues using 3 milestones:

• 1.0 is for work to be completed by the 1.0 release.
• Later is for work to be completed after the 1.0 release.

Issues without a milestone have either not been scheduled or are cleanup work that can be done whenever someone finds the time or inclination.

Frequently Asked Questions (FAQ)

Why the name Cockroach?

It is evocative of the properties of the system we are trying to build. Cockroaches are hard to kill, spread easily, and evolve quickly. “Roach Motel” would also be a great name for a hosting service.
