The simplest way I see so far is using Redis PubSub as a mediator, with node.js server handling HTTP requests and publishing messages to the request channel (via redis-node-client), and Scala actors (e.g. Akka Redis PubSub integration) subscribed the request channel and publi...

When we cache simple objects we do a GET and Redis will return null if the object doesn't exist and we'll know that the object isn't cached and have to be loaded from database. But how do we best handle the same for lists - an empty list can be a vali...
