To ensure uninterrupted operation of your data warehouse during critical business periods, it is recommended that you enable the Deferred Maintenance feature for all of your Amazon Redshift clusters. With this feature, you can defer maintenance for your clusters for up to 14 days, allowing you to schedule maintenance during less busy periods. If your organization runs mission-critical workloads on Redshift, it is important to ensure that scheduled maintenance does not impact your business activities. By deferring maintenance, you can avoid interruptions and ensure that your cluster is available when you need it. Note that if a mandatory hardware replacement is scheduled for your Redshift cluster, the deferred maintenance period will be overridden. In this case, you will receive an event notification via the AWS Management Console and the SNS subscription.
