CockroachDB is a cloud-native distributed SQL database designed to build, scale, and manage modern, data-intensive applications.
CockroachDB is a distributed SQL database built on a transactional and strongly-consistent key-value store. It scales horizontally; survives disk, machine, rack, and even datacenter failures with minimal latency disruption and no manual intervention; supports strongly-consistent ACID transactions; and provides a familiar SQL API for structuring, manipulating, and querying data.
For more details, see our FAQ or architecture document.
For guidance on installation, development, deployment, and administration, see our User Documentation.
We can run CockroachDB for you, so you don't have to run your own cluster.
See our online documentation: Quickstart with CockroachCloud
CockroachDB supports the PostgreSQL wire protocol, so you can use any available PostgreSQL client drivers to connect from various languages.
See our wiki for more details.
