CockroachDB has released a whitepaper demonstrating its high OLTP performance, achieving over 128,000 tpmC on a TPC-C dataset of over 2 terabytes, which is over 10 times the throughput of Amazon Aurora in similar conditions. This performance was achieved in serializable isolation mode, offering both strong isolation and high performance without sacrificing correctness and maintainability. The benchmark, though unofficial and not validated by the Transaction Processing Council, uses a richer set of SQL semantics compared to NoSQL benchmarks. CockroachDB's linear scalability is highlighted, showing that a 10,000 warehouse setup using 30 nodes offers 10 times the throughput of a 1,000 warehouse setup with 3 nodes, demonstrating that operational costs can scale with business needs. The whitepaper adheres to CockroachDB's open-source philosophy by providing a step-by-step guide to reproduce these performance numbers, inviting scrutiny and contributions to ensure transparency and accuracy.
