CockroachDB

CockroachDB is a cloud-native distributed SQL database for modern, data-intensive applications. It is built on a transactional, strongly consistent key-value store and provides a familiar SQL API for structuring, manipulating, and querying data.

It scales horizontally and supports strongly consistent ACID transactions. CockroachDB is designed to survive disk, machine, rack, and datacenter failures with minimal latency disruption and no manual intervention. Core capabilities include data replication, automatic rebalancing, fault tolerance, and recovery.

CockroachDB can run as CockroachCloud, as a manual multi-machine cluster, on cloud platforms, or with open-source orchestration systems. It supports the PostgreSQL wire protocol, so PostgreSQL client drivers can connect from various languages. Versions v24.3 and later are published under the CockroachDB Software License.
