TiDB Operator version: 1.0.0-beta.3

v1.0.0-beta.3 What’s New

Action Required

  • ACTION REQUIRED: nodeSelectorRequired was removed from values.yaml.
  • ACTION REQUIRED: Comma-separated values support in nodeSelector has been dropped, please use new-added affinity field which has a more expressive syntax.

A lot of stability cases added

  • ConfigMap rollout
  • One PD replicas
  • Stop TiDB Operator itself
  • TiDB stable scheduling
  • Disaster tolerance and data regions disaster tolerance
  • Fix many bugs of stability test

New Features

  • Introduce ConfigMap rollout management. With the feature gate open, configuration file changes will be automatically applied to the cluster via a rolling update. Currently, the scheduler and replication configurations of PD can not be changed via ConfigMap rollout. You can use pd-ctl to change these values instead, see #487 for details.
  • Support stable scheduling for pods of TiDB members in tidb-scheduler.
  • Support adding additional pod annotations for PD/TiKV/TiDB, e.g. fluentbit.io/parser.
  • Support the affinity feature of k8s which can define the rule of assigning pods to nodes
  • Allow pausing during TiDB upgrade

Documentation Improvement

  • GCP one-command deployment
  • Refine user guides
  • Improve GKE, AWS, Aliyun guide

Pass User Acceptance Tests
