TiDB Operator 1.2.0 Release Notes

Release date: July 29, 2021

TiDB Operator version: 1.2.0

Rolling update changes

• Upgrading TiDB Operator will cause the recreation of the TidbMonitor Pod due to #4085

New features

• Support setting Prometheus retentionTime, which is more fine-grained than reserveDays, and only retentionTime takes effect if both are configured (#4085, @better0332)
• Support setting priorityClassName in the Backup CR to specify the priority of the backup job (#4078, @mikechengwei)

Improvements

• Changes the default Region leader eviction timeout of TiKV to 1500 minutes. The change prevents the Pod from being deleted when the Region leaders are not transferred completely to the other stores, which will cause data corruption (#4071, @KanShiori)

Bug fixes

• Fix the issue that the URL in Prometheus.RemoteWrite may be parsed incorrectly in TiDBMonitor (#4087, @better0332)
