CockroachDB 1.0 is now available! Get more details in this blog post.

CockroachDB Core

A SQL database designed to grow with you.

Distributed SQL

Get started quickly with distributed SQL that grows with your application

  • Install in seconds and scale horizontally with no application-level changes.
  • Use existing PostgreSQL client drivers or supported ORMs.
  • Interface with a robust SQL API that supports distributed ACID transactions, foreign keys, secondary indexes, JOINs, aggregations, and zero-downtime schema changes.

Always-on services

Maintain data integrity at scale

  • Provide always-on services with multi-active availability, a new standard of availability that uses groups of symmetric nodes to intelligently agree on write success. Once consensus is reached, writes are instantly readable from any node in the cluster.
  • Send R/W traffic to any CockroachDB node - all nodes are symmetric and serve as client gateways.
  • Dynamically load balance to healthy nodes instead of using complex and error-prone failover setups.

Run your application with cloud-native features built-in

  • Achieve greater data redundancy and availability with consistent replication across nodes.
  • Simplify ops with self-organizing nodes that support automatic scaling, failover, replication, and repair.
  • Monitor cluster health and performance through the admin UI.
