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

Allows you to specify the read capacity settings for a replica table or a replica global secondary index when the `BillingMode` is set to `PROVISIONED`. You must specify a value for either `ReadCapacityUnits` or `ReadCapacityAutoScalingSettings`, but not both. You can switch between fixed capacity and auto scaling.

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

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

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

```
{
  "[ReadCapacityAutoScalingSettings](#cfn-dynamodb-globaltable-readprovisionedthroughputsettings-readcapacityautoscalingsettings)" : CapacityAutoScalingSettings,
  "[ReadCapacityUnits](#cfn-dynamodb-globaltable-readprovisionedthroughputsettings-readcapacityunits)" : Integer
}
```

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

```
  [ReadCapacityAutoScalingSettings](#cfn-dynamodb-globaltable-readprovisionedthroughputsettings-readcapacityautoscalingsettings): 
    CapacityAutoScalingSettings
  [ReadCapacityUnits](#cfn-dynamodb-globaltable-readprovisionedthroughputsettings-readcapacityunits): Integer
```
