TiDB Operator v1.0.0-beta.3 Release Notes

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

Features added

• 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 improved

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

Pass Queeny's test

Other improvements

• Upgrade default TiDB version to v3.0.0-rc.1
• fix bug in reporting assigned nodes of tidb members
• tkctl get can show cpu usage correctly now
• Adhoc backup now appends the start time to the PVC name by default.
• add the privileged option for TiKV pod
• tkctl upinfo can show nodeIP podIP port now
• get TS and use it before full backup using mydumper
