CockroachDB may sound like a joke project, but its creators are on a serious mission: Create a distributed SQL database that can scale out well, survive most mishaps (like its namesake is said to be able to survive nearly anything), and make it easy to write applications.
Originally announced back in 2014, CockroachDB is now available in its first public beta. The company behind it, Cockroach Labs, is clearly hoping CockroachDB's design will appeal to creators of database-driven apps.
