CockroachDB: A SQL Database That Survives Disasters
CockroachDB is a distributed SQL database designed to be unkillable. Use it for global apps needing strong consistency and high availability, like financial ledgers or identity systems. The footgun: ignoring network latency between nodes can kill performance.
CockroachDB acts like a traditional PostgreSQL database but runs on a distributed cluster that can span continents. It's built for resilience, automatically surviving disk, machine, or even datacenter failures without data loss. Ideal for global apps needing ACID guarantees, like payment systems or inventory management. The biggest mistake is ignoring physical distance; cross-continent writes incur significant latency due to consensus protocols, so schema design must account for data locality.
