ClickHouse announced the largest expansion of its platform since the launch of ClickHouse Cloud on November 9, 2026: ClickHouse Managed Postgres is now generally available, the company has acquired Xata — the agent-native Postgres company — and new Observability, Security and Langfuse AI Gateway offerings round out a data stack rebuilt for AI agents. Why it matters: agents generate unpredictable, high-volume data workloads, and ClickHouse is positioning one platform to hold the transactions, telemetry, security logs and AI-usage records those agents create.
November 9, 2026 — San Francisco.
Managed Postgres goes GA, and Xata comes with it
ClickHouse Managed Postgres is generally available today in ClickHouse Cloud. Built on NVMe-backed storage, it pairs PostgreSQL for transactions with ClickHouse for real-time analytics, using native change data capture to replicate data into ClickHouse with sub-second latency, plus a pg_clickhouse extension that lets developers query analytical data through a standard PostgreSQL interface. High availability and automated backups are included.
The Xata acquisition is about what comes next: Xata’s technology for instant database branching and cloning, and elastic, scale-to-zero environments. ClickHouse says those capabilities will let developers spin up isolated Postgres environments for development and testing, and lay the foundation for a dedicated tier designed for AI agents — supporting agent sandboxing, agent memory and other agent-first workloads. Xata says nothing changes for its customers in the short term and it continues to accept new sign-ups; customers will eventually be migrated to ClickHouse Managed Postgres once there is feature parity.
Observability in beta, an agentic SIEM in preview
ClickHouse Observability launches in public beta as a fully managed offering for logs, metrics, traces and session data ingested through OpenTelemetry, aimed at teams that want to retain full-fidelity, high-cardinality data instead of sampling it away. ClickHouse points to Mercado Libre as proof of scale: roughly 400 million spans per minute processed on ClickHouse, with 75x faster queries and about 89% compression.
ClickHouse Security, in private preview with access by request, is an agentic SIEM built on technology from RunReveal, which ClickHouse acquired in September. Native AI agents triage alerts, query the underlying logs and write their findings and reasoning back to the case, and security teams can investigate in natural language. The offering connects over one hundred cloud, identity and SaaS sources through first-party integrations.
Langfuse AI Gateway targets the AI bill
Langfuse — the open-source AI engineering platform ClickHouse acquired in January, now at more than 35,000 GitHub stars and over 90 million package downloads per month — is launching its AI Gateway in public beta. Routing model requests through the gateway automatically traces AI usage and costs with zero code changes, giving platform and finance teams visibility into which models are being used, by whom and at what cost. The gateway is built in Rust and available self-hosted or on Langfuse Cloud.
Why it matters
ClickHouse now serves more than 5,000 customers, including DoorDash, Ramp, Meta, Tesla, Cisco and Visa. The pattern across all four announcements is the same one competitors like Snowflake are chasing: agents are becoming the hungriest users of enterprise data infrastructure, and the vendors want to own every layer those agents touch — including, in Xata’s case, letting agents provision their own database environments. The catch for buyers is maturity: only Managed Postgres is generally available today. Observability is a beta, Security is a private preview, and the agent-native Postgres features that make the Xata deal interesting are roadmap, not product. Everything AI, tested: judge this launch on the GA piece now, and on whether the agent tier ships as promised.
