Recently we launched an integration with LangChain, the most popular orchestration framework for developing applications with large language models, to simplify development of production-ready agentic AI applications with CockroachDB. This integration provides out-of-the-box support for CockroachDB as a vector source for any LangChain user using LangChain Python.

Fintech is one of the most competitive and highly regulated industries in the world. Whether you’re a payment processor, digital-first bank, trading platform, or wallet provider, your infrastructure is directly tied to customer trust. In this environment, outages aren’t just technical incidents; a single missed transaction, delayed authorization, or moment of downtime can erode customer confidence instantly.

In betting and gaming, growth is rarely gradual. Traffic spikes around major sporting events. Millions of real-time transactions hit your platform at once, and every one of them has to be correct. When the database falters, the consequences aren’t abstract. Revenue stops. Players lose trust. Regulators start asking questions.

Every year at RoachFest, we hear directly from the teams running some of the most demanding data workloads in production. RoachFest 2025 was no different—except this year, a clear theme emerged across customer sessions: primary data and metadata are often mission-critical.

83% of technology leaders believe their infrastructure will fail under AI pressure within two years. That number is not meant to provoke alarm. It’s simply a fact that reflects the forward-looking judgment of 1,125 global engineering and technology leaders who are already seeing stress where their systems were never designed to carry it.

AI agents are no longer a thought experiment. They’re already writing code, calling APIs, retrying failed requests, and coordinating work at machine speed. And they’re about to put unprecedented pressure on the systems we use to store and move data.

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.
