    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. Its data comes solely from syncing with the primary instance, and it must reside in the same region as the primary instance. By default, you can create up to seven read-only instances for a primary instance. To create more than seven read-only instances, please submit a ticket.
