SysEleven MetaKube Operator (MKO) - Release Notes

This page details all releases for our SysEleven MetaKube Operator (MKO) product, with the most recent updates at the top.

2026-05-01 Feature Release "CloudNativePG Replica Cluster"

Version: 1.2.1

Release Notes

We have extended our Managed Service CloudNativePG in the MetaKube Operator environment with technical support for Replica Clusters. This enables PostgreSQL clusters to be continuously replicated from a defined source cluster.

Replica Clusters create new options for disaster recovery, cross-region architectures and read-only workloads, such as reporting and analytics. The concrete usage depends on the target architecture, technical prerequisites and the agreed service scope.

New Capabilities

Replica Cluster Support

  • Continuous replication of a PostgreSQL cluster from a defined source cluster
  • Support for disaster recovery scenarios and cross-region architectures
  • Usage as a read-only cluster for reporting and analytics workloads

Replication & Recovery

  • Implementation via streaming replication depending on the target architecture
  • WAL-based recovery via Object Storage possible
  • Combination of streaming replication and WAL-based recovery possible

Managed Service Scope

  • Provided as part of the Managed Service CloudNativePG on MetaKube Operator
  • Scenario-based usage depending on architecture, prerequisites and service scope
  • Suitable for customers with requirements around resilience, distribution and reporting

Notes

  • Replica Clusters are not a standard feature of every CloudNativePG deployment
  • Usage requires a prior technical assessment of the target architecture
  • Active write operations remain on the source cluster
  • Failover, recovery and operational processes depend on the agreed architecture and service concept
