What is Amazon Redshift

Amazon Redshift is a cloud-based, fully managed data warehouse service designed for petabyte-scale operations. With Amazon Redshift Serverless, you can analyze and access data without dealing with the complexities of setting up a provisioned data warehouse. The service automatically provisions resources, and the data warehouse capacity adapts intelligently to ensure rapid performance for challenging and unpredictable workloads. Charges are only incurred when the data warehouse is active, allowing you to pay solely for the resources you utilize during usage, with no costs during idle periods.

You have the option to restore a snapshot created on the Amazon Redshift Serverless console to a provisioned Amazon Redshift cluster. During this process, you can select the node type (e.g., RA3) and determine the number of nodes, giving you control over settings at either the cluster or node level. To initiate the restoration, you choose a snapshot from the Amazon Redshift Serverless console and specify the ID of the provisioned cluster for the restoration.

For restoring a provisioned cluster snapshot to a serverless namespace, begin from the Redshift provisioned console. Select the snapshot to restore, then opt for “Restore from snapshot” and “Restore to serverless namespace.” Amazon Redshift converts tables with interleaved keys into compound sort keys when restoring a provisioned cluster snapshot to a serverless namespace. Additional information about sort keys is available in the “Working with sort keys” documentation.

When restoring a snapshot to a serverless namespace, the process replaces the existing database with the database stored in the snapshot. Furthermore, recovery points…
