# AWS::DynamoDB::GlobalTable ReplicaStreamSpecification
<a name="aws-properties-dynamodb-globaltable-replicastreamspecification"></a>

Represents the DynamoDB Streams configuration for a global table replica.

## Syntax
<a name="aws-properties-dynamodb-globaltable-replicastreamspecification-syntax"></a>

To declare this entity in your CloudFormation template, use the following syntax:

### JSON
<a name="aws-properties-dynamodb-globaltable-replicastreamspecification-syntax.json"></a>

```
{
  "[ResourcePolicy](#cfn-dynamodb-globaltable-replicastreamspecification-resourcepolicy)" : {{ResourcePolicy}},
  "[Tags](#cfn-dynamodb-globaltable-replicastreamspecification-tags)" : {{[ Tag, ... ]}}
}
```

### YAML
<a name="aws-properties-dynamodb-globaltable-replicastreamspecification-syntax.yaml"></a>

```
  [ResourcePolicy](#cfn-dynamodb-globaltable-replicastreamspecification-resourcepolicy): {{
    ResourcePolicy}}
  [Tags](#cfn-dynamodb-globaltable-replicastreamspecification-tags): {{
    - Tag}}
```

## Properties
<a name="aws-properties-dynamodb-globaltable-replicastreamspecification-properties"></a>

`ResourcePolicy`  <a name="cfn-dynamodb-globaltable-replicastreamspecification-resourcepolicy"></a>
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.  
*Required*: No

`Tags`  <a name="cfn-dynamodb-globaltable-replicastreamspecification-tags"></a>
Specifies the tags to apply to the DynamoDB stream for this global table replica. Stream tags are independent of table and replica tags.
