IONOS Cloud updates and patches your In-Memory DB instance to achieve high standards of functionality and security. This includes minor patches for In-Memory DB and patches for the underlying operating system. Generally, these updates are unnoticeable and do not interrupt your operation. However, occasionally, IONOS restarts your In-Memory DB instance to allow the changes to take effect.
Prepare for a downtime during the version upgrade.
Ensure the instance has enough available storage. While the upgrade is space-efficient (because it does not copy the data directory), some temporary data is written to the disk.
Note:
Updates to a new minor version are always backward compatible. Such updates are done during the maintenance window with no additional actions from your end.
Failure to configure persistence for a single instance might result in data loss.
Currently, IONOS DBaaS only supports minor upgrades for In-Memory DB. All changes that may cause service interruption (like upgrades) are executed within the maintenance window, which is a weekly four-hour window. During the maintenance window, you may experience uncontrolled disconnections and an inability to connect to the In-Memory DB instance. Such disconnections are destructive for any ongoing transactions and we recommend that you reconnect.
You can configure a maintenance window during the In-Memory DB instance creation using the same API request. For more information, see Create an In-Memory DB Instance. You can also configure one when you modify the existing In-Memory DB instance. For more information, see Modify an In-Memory DB Instance.
