Amazon Redshift launches cross-instance restore
Amazon Redshift now supports cross-instance restore to allow you to restore Redshift snapshots to clusters that are different sizes or running different node types. This simplifies snapshot restore workflows to support your evolving use cases. You can change instance type and count based on compute resources, storage capacity and cost requirements of your specific workloads. For example, you can cross-instance restore a snapshot of your production dense-compute cluster with small instances into a cluster with powerful large instances to serve more demanding workloads, or to a lower-cost development cluster. Once a cluster is restored, you can resize it as your performance and capacity needs change over time.
