AWS API Gateway caching is disabled

Description

A cache cluster caches responses. With caching, you can reduce the number of calls made to your endpoint and also improve the latency of requests to your API.

Fix - Runtime

1. Go to the API Gateway console.
2. Select an API.
3. Select Stages.
4. In the Stages list for the API, select the required stage.
5. Go to the Settings tab.
6. Select Enable API cache.
7. Wait until cache creation is complete.

Fix - Buildtime
