# AWS::Cassandra::Table ReplicaSpecification
<a name="aws-properties-cassandra-table-replicaspecification"></a>

The AWS Region specific settings of a multi-Region table.

For a multi-Region table, you can configure the table's read capacity differently per AWS Region. You can do this by configuring the following parameters.
+ `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 CloudFormation template, use the following syntax:

### JSON
<a name="aws-properties-cassandra-table-replicaspecification-syntax.json"></a>

```
{
  "[ReadCapacityAutoScaling](#cfn-cassandra-table-replicaspecification-readcapacityautoscaling)" : AutoScalingSetting,
  "[ReadCapacityUnits](#cfn-cassandra-table-replicaspecification-readcapacityunits)" : Integer,
  "[Region](#cfn-cassandra-table-replicaspecification-region)" : String
}
```

### YAML
<a name="aws-properties-cassandra-table-replicaspecification-syntax.yaml"></a>

```
  [ReadCapacityAutoScaling](#cfn-cassandra-table-replicaspecification-readcapacityautoscaling): 
    AutoScalingSetting
  [ReadCapacityUnits](#cfn-cassandra-table-replicaspecification-readcapacityunits): Integer
  [Region](#cfn-cassandra-table-replicaspecification-region): String
```
