CockroachDB is a horizontally and vertically scalable SQL database that ensures continuous access to data even in the face of hardware failures, network issues, or regional outages. It provides operational excellence through automated operations like sharding, rebalancing, backups, and rolling upgrades, reducing manual effort and minimizing downtime. The database delivers security with encryption by default for data at rest and in transit, role-based access control (RBAC), and audit logging to meet stringent compliance requirements. For resilience, its distributed SQL architecture ensures fault tolerance and continuous availability through automated replication and failover, even across multi-region deployments. CockroachDB achieves performance with intelligent query optimization, efficient indexing strategies, and geo-partitioning to minimize latency and ensure fast, consistent access to data globally. It also optimizes costs by leveraging commodity hardware, elastic scalability, and automated operations to align infrastructure costs with demand, ensuring efficiency without compromising performance or reliability.
