VoltDB Operator Release Notes

The VoltDB Operator automates and simplifies deploying and managing VoltDB clusters on Kubernetes. The following are notes related to the individual releases of the VoltDB Operator. A chart listing version compatibility between the Operator, Helm charts and the VoltDB software for current and past releases can be found in the VoltDB software Release Notes.

Version 1.3.5 (June 16, 2021)

  • Support for Kubernetes 1.20.
  • The VoltDB Operator now logs all of the commands it issues to the VoltDB processes.
  • Setting the property cluster.clusterSpec.deletePVC to false then uninstalling the release now clears all metadata to avoid old metadata accidentally being reused when a new release is installed.
  • Fix an issue with XDCR where repetitive health checks on the DR port could flood the logs with warnings and interfere with regular client connections. A similar condition when enabling SSL on the VoltDB cluster was also fixed.

Version 1.3.4 (May 7, 2021)

  • The Operator only supports XDCR, not passive DR. Setting the cluster.config.deployment.dr.role property to anything but xdcr or none is now reported as an error.

    Version 1.3.3 (March 25, 2021)

  • Support for Kubernetes 1.19.

Version 1.3.2 (March 2, 2021)

  • Support for the inclusion of initialization schema, procedure classes, and third-party JAR files through the additionalVolumes and additionalVolumeMounts properties.
  • The VoltDB httpd interface is now managed as a separate service {cluster-name}-http. This service has session affinity enabled for the client IP address to allow use of nodeports for accessing VMC.
