EDB moves CloudNativePG into CNCF incubation and adds Klio backup
EDB says CloudNativePG, its open source Kubernetes operator for Postgres, has entered CNCF Incubation, marking a new stage of independent recognition for the project. The company is also donating its Klio backup technology to the CNPG community and previewing enterprise tools designed to reduce data loss and add capabilities without replacing the operator.
- CloudNativePG has entered CNCF Incubation.
- EDB is donating Klio to the CNPG community.
- Klio streams WAL continuously for near-zero data loss.
- EDB is previewing a Postgres AI Plugin for CNPG.
- Integrated enterprise ClickHouse capabilities are planned for Q4 2026.
CloudNativePG gains CNCF Incubation
CloudNativePG was created in 2019 and open sourced in 2022. EDB describes it as the most widely adopted operator for managing the full lifecycle of Postgres clusters on Kubernetes.
According to EDB, the Cloud Native Computing Foundation announced on November 10 that CNPG had reached Incubation. It is the only Postgres operator to do so, according to the company. CNCF Incubation requires stable, versioned APIs and production use verified through interviews with real users.
CNPG supports declarative deployment across cloud and on-premises environments. Its features include self-healing, automated failover, rolling updates, continuous backup and point-in-time recovery. EDB remains the project's primary maintainer and extends its enterprise capabilities through EDB Postgres AI for CloudNativePG.
EDB says 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 is also built on CNPG.
Klio targets backup and recovery gaps
EDB is donating Klio to the CNPG community to provide backup and recovery with near-zero data loss for open source Postgres on Kubernetes. The company says CNPG's built-in backup options archive write-ahead log, or WAL, data only as completed segments, meaning an outage can result in up to five minutes of lost transactions.
Klio streams WAL continuously instead of waiting for completed segments. It also keeps a local copy beside the cluster, allowing restores to run at disk speed rather than requiring a full copy to be pulled from remote storage for every request. The software encrypts data in transit and at rest, supports rotatable customer-controlled keys, and lets users store backups on local volumes, S3-compatible storage, or both.
One Klio server can protect multiple clusters and display the health of each backup in one place. Ahead of general availability, EDB is previewing an EDB distribution of Klio with certified images, support and long-term releases.
One Kubernetes model for Postgres and ClickHouse
The announcement follows EDB's acquisition of Altinity, creator of the Altinity Kubernetes Operator for ClickHouse software. EDB says the deal brings two teams together around Kubernetes support for Postgres and ClickHouse software. The Altinity operator has been maintained since 2019 and has been pulled more than 108 million times from Docker Hub, according to EDB.
EDB plans to combine the operators under its EDB Postgres AI data layer, allowing teams to manage transactional workloads on Postgres and real-time analytics on ClickHouse software with one operating model. The company says an example could involve payments on Postgres and fraud analytics on ClickHouse software, fed by change data capture.
EDB is also previewing a new EDB Postgres AI Plugin for CloudNativePG. It is designed to add enterprise features such as transparent data encryption to open source CNPG without an operator swap. Both the plugin and the EDB distribution of Klio are planned for general availability by the end of 2026, while community images remain free. EDB also plans to introduce integrated enterprise ClickHouse capabilities in Q4 2026.
