300-Node Clusters Now Supported in CockroachDB

CockroachDB's recent update, v25.4.4, introduces support for 300-node clusters with 2.2 million tpmC and 1.2 petabytes of data, alongside 64 vCPU per node on CockroachDB Cloud, aiming to eliminate the trade-off between correctness, simplicity, and scale in data platforms. The company highlights its commitment to resilience and scale as core aspects of its value proposition, having previously achieved significant latency improvements and now measuring scale to inform engineering practices and customer recommendations. Extensive testing on the latest release demonstrated capabilities under operational stressors such as disk stalls and network partitions, showing near-linear scalability and improved storage efficiency, while maintaining consistent performance during chaos testing. Future plans involve expanding cluster sizes and data capacities, enhancing observability and supportability, and providing clear guidelines for scaling infrastructure to meet growing data demands driven by AI applications.
