Description

Summary

AWS::RedshiftServerless::Namespace currently does not support snapshot restore functionality via CloudFormation, forcing users to rely on manual AWS CLI operations for disaster recovery and environment promotion scenarios.

Service

Amazon Redshift Serverless

Resource Type

AWS::RedshiftServerless::Namespace

Current Limitation

The AWS::RedshiftServerless::Namespace resource type lacks properties to restore from existing snapshots. Currently, only new namespace creation is supported.

Requested Properties

Add the following properties to AWS::RedshiftServerless::Namespace:

• SnapshotName (String, Optional) - Name of the snapshot to restore from (same account)
• SnapshotArn (String, Optional) - Full ARN of the snapshot to restore from (cross-account support)

When either property is specified:

• DbName, AdminUsername, and AdminUserPassword should be optional/ignored (restored from snapshot)
• The namespace should be created from the specified snapshot instead of as a new empty namespace

Use Cases

1. Disaster Recovery: Restore production data to a new environment from snapshots
2. Environment Promotion: Copy data from prod to staging/dev environments
3. Cross-Account Data Sharing: Restore snapshots shared from other AWS accounts
4. Infrastructure as Code: Manage complete Redshift Serverless lifecycle via CloudFormation

Current Workaround

Manual AWS CLI operations:

aws redshift-serverless restore-from-snapshot \
  --namespace-name "my-namespace" \
  --snapshot-arn "arn:aws:redshift-serverless:us-east-1:123456789012:snapshot/snapshot-id"
