CockroachDB
Specific characteristics

CockroachDB is a DistributedSQL database architected for modern cloud applications. It implements a standard, developer-friendly SQL interface and provides linear, automated scale for your data without the labor intensive overhead of manual sharding. CockroachDB replicates data across multiple nodes so that even with the loss of a node or region, you can be sure data is always available and transactions can always be committed. It guarantees distributed, transactional consistency at local and global scale and provides the ability to tie data to a location so you can counter latency issues and comply with data privacy regulations. Cockroach Labs has three software products (CockroachDB Core, CockroachDB Enterprise, and CockroachCloud) and an educational offering (Cockroach University).

Competitive advantages
- EFFORTLESS SCALE: Scale your applications, not operational complexity. CockroachDB scales without manual operation, eliminates overhead associated with manual sharding, and balances server utilization to reduce costs.
- BULLETPROOF RESILIENCE: Ensure your apps are always on and available. CockroachDB survives system failures without interruption, reduces the need for complex and costly backup configurations, and eliminates the risk of losing data.
- ENSURED CONSISTENCY: Guarantee transactional consistency in distributed SQL. CockroachDB ensures all your data is always correct and up-to-date, guarantees serializable isolation, and applies a cost-based optimizer and query planner to distributed workloads.
- GEO-LOCALITY: Give your data a location. CockroachDB is the only database that assigns data to a location allowing you to reduce latencies, move data close to your customers, and remain globally compliant.
Typical application scenarios

System of record (financial ledger, inventory management, transaction record), identity access management (IAM), metadata layer, general purpose DB
