## AI overview

Cockroach Labs announces support for 300-node clusters in CockroachDB v25.4.4 and later, with up to 2.2M tpmC and 1.2PB of data. The article also describes testing involving operational stress and reports performance results from that test cycle.

## Source excerpt

As AI-driven and agentic applications push data platforms into new territory, data architects are increasingly forced to choose between correctness, simplicity, and scale. Today, we're removing that tradeoff -- announcing support for 300-node clusters with 2.2M tpmC and 1.2PB of data in CockroachDB v25.4.4 and beyond. On CockroachDB Cloud, we're announcing support for 64 vCPU per node. Testing to this scale is important to ensure that we're testing ahead of customer deployments, and this milestone does just that. We believe these tests represent the largest node-scale testing completed by any distributed SQL vendor. And we're just getting started.
