MemoryDB automatically monitors your fleet of clusters and nodes to apply service updates as they become available. Typically, you set up a predefined maintenance window so that MemoryDB can apply these updates. However, in some cases you might find this approach too rigid and likely to constrain your business flows.
With Service updates in MemoryDB, you control when and which updates are applied. You can also monitor the progress of these updates to your selected MemoryDB cluster in real time.
Applying the service updates using the AWS CLI
After you receive notification that service updates are available, you can inspect and apply them using the AWS CLI:
-
To retrieve a description of the service updates that are available, run the following command:
aws memorydb describe-service-updates --status availableFor more information, see describe-service-updates.
-
To apply a service update on a list of clusters, run the following command:
aws memorydb batch-update-cluster --service-update ServiceUpdateNameToApply=sample-service-update --cluster-names cluster-1 cluster2For more information, see batch-update-cluster.
