TiDB Operator 1.1.3 Release Notes

Release date: July 27, 2020

TiDB Operator version: 1.1.3

Action Required

• Add a field cleanPolicy in BackupSpec to denote the clean policy for backup data when the Backup CR is deleted from the cluster (default to Retain). Note that before v1.1.3, TiDB Operator will clean the backup data in the remote storage when the Backup CR is deleted, so if you want to clean backup data as before, set spec.cleanPolicy in Backup CR or spec.backupTemplate.cleanPolicy in BackupSchedule CR to Delete. (#3002, @lichunzhu)

• Replace mydumper with dumpling for backup.

  If spec.mydumper is configured in the Backup CR or spec.backupTemplate.mydumper is configured in the BackupSchedule CR, migrate it to spec.dumpling or spec.backupTemplate.dumpling. After you upgrade TiDB Operator to v1.1.3, note that spec.mydumper or spec.backupTemplate.mydumper will be lost after the upgrade. (#2870, @lichunzhu)
