(dynamodb): deletion policy not applied to replicas from global tables

[esiefkas]

Describe the bug

When provisioning a DynamoDB table with replication enabled, the removal policy is only applied to the primary table, not the replicas.

Expected Behavior

All tables (primary and replicas) should have the same removal policy applied.

Current Behavior

Primary has the selected deletion policy applied, all replicas have the DESTROY deletion policy

Reproduction Steps

const globalTable = new dynamodb.Table(this, 'Table', {
  partitionKey: { name: 'id', type: dynamodb.AttributeType.STRING },
  replicationRegions: ['us-east-1', 'us-east-2', 'us-west-2'],
  billingMode: dynamodb.BillingMode.PROVISIONED,
  removalPolicy: RemovalPolicy.RETAIN,
});

Possible Solution

This may be intended? If so what is the rationale?

This is similar to this issue #18582, in that we use custom resources to implement this instead of the CfnGlobalTable resource. That could potentially be a better choice here. The way CDK typically sets deletion policy is through the CfnResource DeletionPolicy attribute, which resources created through custom resources can't make use of.

On a quick look through the docs Adam linked related to the SDK call, I wasn't able to find anything related to deletion policy. Do you know of a way to do this with the SDK call we're using?

Thanks for opening the issue @esiefkas. This is a duplicate of #17011, so let's try to keep the conversation there 🙂.

Thanks,
