MysqldbHaClusterConfigInput

Supported in v9.6+ HA cluster configuration for a MySQL instance with one or more replicas.

Fields

Field	Type	Description
backupNodePreference	BackupNodePreferenceInput	Supported in v9.6+ Optional customer preference for which replica(s) the backup scheduler picks as the source. When absent or null in the request body the stored value is left unchanged. When present it is validated and persisted. Note: HA clusters use the shared unsorted.kosmos_models.BackupNodePreference object (a strategy enum with values PRIMARY_ONLY, STANDBY_ONLY, ANY, or PREFER_STANDBY, plus orderedReplicaPreferences and excludedReplicaIds). This is intentionally distinct from the standalone MysqldbBackupPreference string enum (Primary or ReplicaOnly), which applies only to non-HA instances.
replicas	[MysqldbHaReplicaConfigInput!]!	Required. Supported in v9.6+ List of replicas in this HA cluster. On a patch, send only the replicas you want to change: replicas not included are left unchanged, and a replica is removed only via an explicit shouldDeleteReplica. At most one replica may carry a PRIMARY role hint; zero is allowed (all-standby clusters are supported).
