PXC Removal in Alauda Database Service for MySQL v4.3.0

MySQL-PXC is deprecated and removed starting from Alauda Database Service for MySQL v4.3.0. Existing PXC instances will continue running but are no longer managed by the MySQL operator. If you have PXC instances, you must migrate them to MySQL-MGR before upgrading to MySQL Operator v4.3.0 or later.

  • Migration Guide: See Migrate MySQL-PXC to MySQL-MGR for comprehensive step-by-step instructions covering schema compatibility, character sets, users, and privileges.
  • MySQL Operator Upgrade Guide: See Upgrade Guide for pre-upgrade checklists, upgrade scenarios, and emergency response procedures.

Alauda Container Platform Data Services Essentials are designed to upgrade automatically during platform upgrades, requiring no manual intervention. The system handles all necessary migrations and updates seamlessly in the background.

Alauda Container Platform Data Services RDS Framework will execute upgrades based on the configured upgrade strategy:

  • Automatic: Auto-upgrades are triggered immediately upon detecting new component versions.
  • Manual: Requires manual approval before initiating the upgrade process.
WARNING

When upgrading ACP from v3 to v4, it is recommended to promptly upgrade both the global cluster and workload clusters to the new version to ensure proper display of Data Services view. If only the global cluster is upgraded to v4 while workload clusters remain on v3, please contact the technical team during this period to obtain mitigation steps for view display issues in unupgraded workload clusters.
