### Description{% #description %}

API Gateway stages should have cache clustering enabled to reduce repeated backend requests and lower latency, helping prevent backend overload and service degradation. The `CacheClusterEnabled` property on `AWS::ApiGateway::Stage` resources must be defined and set to `true`. Resources missing this property or with `CacheClusterEnabled` set to `false` will be flagged. The `CacheClusterSize` property should also be configured to provision adequate cache capacity for expected traffic.

Secure configuration example:

```yaml
MyStage:
  Type: AWS::ApiGateway::Stage
  Properties:
    StageName: prod
    RestApiId: !Ref MyApi
    CacheClusterEnabled: true
    CacheClusterSize: '0.5'
```
