Redis is a distributed key/value store key:1 key:2 key:3 key:4 key:5 Value 1 Value 2 Value 3 Value 4 Value 5 App.

Redis as a cache Application Redis >> GET my-cache >> SET my-cache value EX 60 null << OK << var value = cache.get("my-cache"); if (value == null) { value = compute(); cache.set("my-cache", value, Duration.ofSecond(60)); } return value; Application Redis >> GET my-cache Value <<
