2022-06-07

Release v1.2.2.

This is a bugfix release.

Fix DN scale up/down and upgrade issue. Fix grafana memory usage panel when deployed on minikube. Create xstore of DN in parallel. Fix node selector issue for polardbx-monitor. Disable service links in pod spec. Fix overriding my.cnf passing to the script without section.

2022-04-11

Release v1.2.1.

This is a bugfix release.

  • Fix the CDC problem by setting the 'consensuslog_revise' variable of galaxyengine to ON.
  • Update docker registry mirror used in China mainland from ustc to sjtug.
  • Fix the scale in/out progress: use "schedule rebalance" command.

2022-03-31

Release v1.2.0.

  • Enhancement & New Features

    • Provide a new CR PolarDBXMonitor for declaring the monitoring of some PolarDBXCluster. The controller will create ServiceMonitors to make prometheus scraping the metrics.
    • Provide a new chart polardbx-monitor which packages a customized kube-prometheus release with predefined dashboards for monitoring PolarDB-X clusters.
    • Provide support for xpaxos version of galaxyengine. Now the PolarDBXCluster controller will create a typical paxos cluster (leader + follower + logger) for each GMS and DN by default.
      • Note this is a breaking change. After the upgrade, the old XStores will be in an unmaintainable state. Update of the GMS/DN is not possible due to incompatible data/log formats. You may have to delete all the PolarDBXCluster in your Kubernetes before/after the upgrade.
      • If you want to keep the compatibility, you can disable this feature by declaring feature gate with negative symbol EnableGalaxyCluster-. After that, no multi-node XStore with galaxy engine can be created.
    • Support scaling up/down and self-healing of the XStores.

  • Bug Fix

    • Fix the behavior of polardbx-exporter when part of the scrape tasks fail.
