EDB, Now the Company Behind the Leading Kubernetes Operators for Both Postgres® and ClickHouse® Software, Deepens Its Open Source Commitment

CloudNativePG (CNPG) earns CNCF Incubation, Klio brings near-zero data loss to the project, and the new EDB Postgres AI Plugin for CloudNativePG adds enterprise-grade capabilities.

SALT LAKE CITY, Nov. 11, 2026 /PRNewswire/ -- EnterpriseDB (EDB), the leading sovereign data and AI company, today announced that CloudNativePG (CNPG), the most widely adopted Kubernetes operator for Postgres, created by the company, is now a CNCF Incubating project. The news comes less than a week after EDB completed its acquisition of Altinity, creator of the Altinity Kubernetes Operator for ClickHouse software, uniting two expert teams committed to hardening the world's two leading open source databases for Kubernetes, the foundation global enterprises have standardized on.

During KubeCon North America 2026, EDB also announced its donation of Klio to the CNPG community, giving enterprises running open source Postgres on Kubernetes backup and recovery with near-zero data loss. Ahead of general availability, EDB is previewing two enterprise releases: the EDB distribution of Klio, with certified images, support, and long-term releases; and a new EDB Postgres AI Plugin for CloudNativePG that makes it easy to adopt enterprise features such as transparent data encryption (TDE) to open source CNPG with no operator swap. Together, these milestones give enterprises what they need to run their most critical data on Kubernetes with confidence: independent validation of maturity, protection against data loss, and the freedom to expand with enterprise capabilities without ever leaving open source.

"The open, sovereign future runs on Kubernetes. Never is this more true than in the financial sector, where data agility across transactional and analytical workloads is critical," said Max Romanenko, CTO, EDB. "The increasing investment in agent workforces in banking, finance, and insurance industries makes this even more important than ever before. By continuing to invest and give back across the open source communities behind Postgres, ClickHouse software, and the cloud-native ecosystem, we give enterprises the foundation to build that future at scale, on infrastructure they own and control."

CloudNativePG reaches CNCF incubation

Created in 2019 and open sourced in 2022, CNPG has become the most widely adopted operator that manages the full lifecycle of Postgres clusters on Kubernetes. Customers choose CNPG for portability and automation: The same declarative manifest runs on any cloud or on-premises environment, while self-healing, automated failover, rolling updates, and continuous backup with point-in-time recovery replace manual DBA work and database provisioning. EDB is still its primary maintainer, and extends its own enterprise capabilities to it with EDB Postgres AI for CloudNativePG.

Global enterprises already run CNPG in production, and Intesa Sanpaolo, Italy's largest bank, manages more than 500 Postgres instances on CNPG. Microsoft's official guide to highly available Postgres on Azure Kubernetes Service (AKS) is built on CNPG.

On November 10, CNCF announced that CNPG has reached Incubation and is the only Postgres operator to do so. This is a significant milestone with vendor-neutral recognition of proven production use, healthy community contributions, and strong governance. Incubation requires stable, versioned APIs and production use that CNCF verifies by interviewing real users of the project. For enterprises looking to operate Postgres across hybrid environments or move critical data to sovereign infrastructure, Incubation is independent confirmation that CNPG runs in production, an important step as enterprises standardize critical workloads on Postgres and Kubernetes.

Klio closes the backup and recovery gaps for CNPG

Near-zero data loss is the bar for any system of record, and until now it has been missing for Postgres on Kubernetes. CNPG's built-in backup options archive Postgres's write-ahead log (WAL) only as completed segments, so an outage can cost up to five minutes of lost transactions. Encryption and disaster recovery depend on infrastructure settings or custom tooling that teams must stitch together themselves. These gaps have kept some of the most critical Postgres workloads off Kubernetes.

EDB built Klio specifically to close those gaps for CNPG and has donated it to the CNPG community. Instead of archiving WAL files in completed segments, Klio streams WAL continuously. While other recovery solutions pull every piece of data back from remote storage, Klio keeps a local copy next to your cluster, so restores run at disk speed and avoid the cost of pulling a full copy from storage on every request.

Klio encrypts customers' data in transit and at rest, using rotatable keys that you control. Klio also lets you choose where your backups live: on local volumes, in the S3-compatible storage you pick for disaster recovery, or both. One Klio server can protect many clusters and shows the health of each backup in one place.

Two operators, two databases, one data layer

More than half of Postgres users already run or are considering ClickHouse software. EDB and Altinity now arrive at KubeCon as one company, bringing the two together in one multi-model data layer, EDB Postgres AI (PG AI), running natively on Kubernetes, as open source, in the customer's own environment.

The Altinity Kubernetes Operator, maintained since 2019 and pulled more than 108 million times from Docker Hub, was the first Kubernetes operator built for real-time analytics. Its design reflects how ClickHouse software scales: It models clusters as shards of peer replicas that all accept writes, runs ClickHouse Keeper as its own managed resource for coordination, and rolls restarts shard by shard while distributed tables route queries around an unavailable replica, so operations proceed without downtime.

Both operators follow the same Kubernetes pattern, declarative resources reconciled in a loop, while doing very different work inside it. That shared pattern is the basis for running both under one control plane, so a team can keep payments on Postgres, run fraud analytics on ClickHouse software fed by change data capture (CDC), and manage both with one operating model and one support relationship. EDB plans to introduce integrated enterprise ClickHouse capabilities in Q4 2026.

At KubeCon, EDB Chief Architect Todd Willey and Altinity CEO Robert Hodges are recording "Two Operators, Two Databases," an upcoming episode of The New Stack podcast on running Postgres and ClickHouse software on Kubernetes.

From open source to enterprise, with no operator swap

At KubeCon, EDB is also previewing two enterprise offerings, both planned for general availability by the end of 2026: an EDB distribution of Klio, with certified images, enterprise support, and long-term-support releases; and an EDB Postgres AI Plugin for CloudNativePG, which makes it easy to add enterprise features such as transparent data encryption to open source CNPG with no operator swap. Community images stay free.

About EDB

EDB Postgres AI (PG AI) is the sovereign AI data system for the agentic enterprise. Built on Postgres, the world's leading open source database, PG AI unifies transactional, analytical, and AI workloads in a single architecture, eliminating the data movement, ETL, and operational fragmentation that slow enterprises down. With governance enforced at the data layer and the flexibility to deploy on-premises, in hybrid environments, or across clouds, enterprises operationalize their data and AI on infrastructure they own and control—reaching production-ready sovereign AI in weeks, not months. As one of the most active contributors to the PostgreSQL project, EDB is deeply invested in the vitality of the global open source community. To learn more, visit www.enterprisedb.com.
