    Instance TypeDefinitionArchitectureVisible in the Instance ListFeature
    Primary instance An instance that can be read from and written to High-Availability edition Yes A primary instance can mount read-only instances for read/write separation
    Read-Only instance An instance that can only be read from Single-Node read-only Yes A read-only instance cannot exist on its own. Instead, it must be affiliated to a primary instance.
