The CloudNativePG Community is thrilled to unveil version 1.22.0 of the CloudNativePG Operator, a significant milestone featuring the introduction of declarative tablespaces and temporary tablespaces alongside various enhancements and fixes.
Tablespaces, a powerful and widely adopted feature in database management
systems, now take center stage in CloudNativePG 1.22.0. This release empowers
users to boost the vertical scalability of their databases by decoupling the
physical and logical data modeling, achieving optimal performance through
parallel on-disk read/write operations. With CloudNativePG, users can define
additional tablespace volumes, and also ensure they can be used for temporary
operations (CloudNativePG seamlessly manages the
This marks a pivotal step towards adopting Very Large Databases, building upon the foundation laid by Kubernetes volume snapshots introduced in version 1.21.
Starting from version 1.22.0, the
ALTER SYSTEM command is now disabled by
default. This ensures that changes to the PostgreSQL configuration are
orchestrated through the Kubernetes API. This streamlined approach guarantees
coherence across the entire high-availability cluster and aligns with best
practices for Infrastructure-as-Code.
In terms of security, all supported versions now require TLS 1.3 for PostgreSQL connections by default, further bolstering the integrity of data transmission.
Before initiating an upgrade, carefully review the detailed instructions. New patch releases are now available for all supported versions, including 1.21.2 and 1.20.5.
Considering the notable changes introduced, we strongly recommend upgrading to CloudNativePG 1.22.0 at your earliest convenience. Alternatively, update to the latest patch version within your current minor release.
With the release of 1.22.0, the 1.20.x minor version will reach its end of life on January 21, 2024.
