Description

Summary

Request to add FinalClusterSnapshotIdentifier and SkipFinalClusterSnapshot properties to the AWS::Redshift::Cluster CloudFormation resource to enable automatic final snapshot creation when clusters are deleted via CloudFormation stack deletion.

Use Case

Currently, when a Redshift cluster is deleted through CloudFormation stack deletion, there's no way to automatically create a final snapshot. This forces users to either:

1. Manually delete the cluster via CLI/Console with snapshot options before deleting the stack
2. Risk data loss if the stack is accidentally deleted
3. Use workarounds like Lambda functions in custom resources

Proposed Solution

Add the following properties to AWS::Redshift::Cluster:

FinalClusterSnapshotIdentifier: String
SkipFinalClusterSnapshot: Boolean

These properties already exist in the Redshift API (delete-cluster operation) but are missing from the CloudFormation resource.

Example Usage

rRedshiftCluster:
  Type: AWS::Redshift::Cluster
  Properties:
    # ... existing properties
    FinalClusterSnapshotIdentifier: !Sub "${ClusterName}-final-snapshot"
    SkipFinalClusterSnapshot: false

Benefits

• Prevents accidental data loss during stack deletion
• Aligns CloudFormation capabilities with native Redshift API
• Eliminates need for complex workarounds
• Improves infrastructure-as-code best practices

Current Workaround

Currently using manual cluster deletion or custom Lambda resources, which adds complexity and potential for human error.

CLI Command (works but requires manual intervention)

aws redshift delete-cluster \
  --cluster-identifier my-cluster \
  --final-cluster-snapshot-identifier my-cluster-final-snapshot

AWS Service
