Hi, I am trying to implement caching to my FF4J server. I have looked through the documentation with no luck. Has anyone here tried to cache their ff4j feature stores? If yes, would you have a code sample for it? Also, how to test that the api call is getting response from the cache and not from DB? I am using ff4j-spring-boot-starter which gives everything out of the box, so I do not have control over a lot of things.
