+ `region`: The Region where these settings are applied. (Required)
+ `readCapacityUnits`: The provisioned read capacity units. (Optional)
+ `readCapacityAutoScaling`: The read capacity auto scaling settings for the table. (Optional)

## Syntax
<a name="aws-properties-cassandra-table-replicaspecification-syntax"></a>

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

### JSON

  "[Region](#cfn-cassandra-table-replicaspecification-region)" : {{String}}
}
```

### YAML
