## Properties

- `resourcePolicy`: [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) | [CfnGlobalTable.ResourcePolicyProperty](/cdk/api/v2/docs/aws-cdk-lib.aws_dynamodb.CfnGlobalTable.ResourcePolicyProperty.html) — A resource-based policy document that contains the permissions for the specified stream of a DynamoDB global table replica.

  Resource-based policies let you define access permissions by specifying who has access to each resource, and the actions they are allowed to perform on each resource.

  In a CloudFormation template, you can provide the policy in JSON or YAML format because CloudFormation converts YAML to JSON before submitting it to DynamoDB . For more information about resource-based policies, see [Using resource-based policies for DynamoDB](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/access-control-resource-based.html) and [Resource-based policy examples](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/rbac-examples.html) .

  You can update the `ResourcePolicy` property if you've specified more than one table using the [AWS ::DynamoDB::GlobalTable](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-dynamodb-globaltable.html) resource.

- `tags`: [CfnTag](/cdk/api/v2/docs/aws-cdk-lib.CfnTag.html)[]
