Amazon Redshift now enables cluster relocation by default for RA3 provisioned clusters - devamazonaws.blogspot.com

Amazon Redshift now enables cluster relocation by default for RA3 provisioned clusters when creating new clusters or restoring from snapshots. This feature allows you to move a cluster to another Availability Zone (AZ) when resource constraints disrupt cluster operations, maintaining the same endpoint so applications continue without modifications.

Amazon Redshift already provides resiliency by automatically detecting and recovering from drive and node failures. Cluster relocation adds another layer of availability protection against AZ-level issues that might prevent optimal cluster operations. While this setting is now enabled by default for new or restored clusters, existing RA3 provisioned clusters maintain their current configuration unless manually changed. You can manage cluster relocation settings through the AWS Management Console, AWS CLI, or API.

This feature is available at no additional cost for RA3 provisioned clusters across all AWS Regions where RA3 instance types are supported. For more information about cluster relocation, visit our documentation page.
