Changes in MySQL Operator for Kubernetes 9.3.0-2.2.4 (2025-05-09, Innovation Release)

Functionality Added or Changed

• For the Enterprise Edition only: MySQL Operator for Kubernetes now supports creating backups to cloud storage using the MySQL Enterprise Backup tool, and restoring such backups to server instances in InnoDB Clusters. Backups can be one-off or scheduled, and both full and incremental backups are supported.

  Note

  Backup to S3 is only supported on the AWS home region.

  (WL #16632, WL #16633)

• For the Enterprise Edition only: MySQL Operator for Kubernetes now supports the creation of InnoDB ClusterSet, which consists of a primary InnoDB Cluster and zero or more replica clusters. Within each ClusterSet, data is replicated from the primary to the replica clusters by asynchronous replication channels. MySQL Operator for Kubernetes can trigger a switchover, replacing a primary cluster by its replica cluster. Emergency failovers of the primary clusters are also supported.

  Each InnoDB Cluster is put into an InnoDB ClusterSet when it is created by MySQL Operator for Kubernetes: It can either be in a new ClusterSet as its single and primary cluster, or it can join a specific, pre-existing ClusterSet as a replica cluster. (WL #16661)
