CockroachDB: Open-Source Distributed SQL Database
An open-source, distributed SQL database offering horizontal scaling, high availability, and ACID transactions for scalable and consistent data management across multiple datacenters.
What is CockroachDB?
CockroachDB is an open-source, distributed SQL database that provides scalability, survivability, and data consistency across multiple datacenters. Some key features include:
- Distributed architecture that scales horizontally
- Automated replication and failover for high availability
- Support for strongly consistent ACID transactions
- Geographic distribution of data across multiple datacenters
- Automatic rebalancing and repair after failures
- SQL interface with support for legacy database workloads
