+# Redis Cache
+
+This project provides an example Redis cache implementation in Knot.x.
+
+It was created with [Knot.x Starter Kit](https://github.com/Knotx/knotx-starter-kit).
+
+## Run
+Build and run docker swarm:
+
+```bash
+./gradlew build
+docker swarm init
+docker stack deploy -c redis-handler.yml redis-handler
+```
+
+## Endpoints
+
+There is one endpoint `GET /book` that calls Google Books API. It's value is cached for 20 seconds.
+
+You can check the logs with
+
+```bash
+docker service logs redis-handler_knotx
+```
+
+Open [localhost:8092/book](http://localhost:8092/book). In the logs there should be:
+
+```
+No valid cache for key: the-book, calling the action
+New value cached under key: the-book for 20 seconds
+```
+
+After refresh the value will be retrieved from Redis and Google Books API won't be called:
+
+```
+Retrieved value from cache under key the-book
+```
+
+And after waiting 20 seconds and refreshing the Google API will be called again, because the cache will be invalidated:
+
+```
+No valid cache for key: the-book, calling the action
+New value cached under key: the-book for 20 seconds
+```
