Summary
In this chapter, we built a network application that cached chat logs. Our network application also has a background task continuously running to periodically clean up the cache by sending the cached data to a server. We broke down and created our background task runner into an actor system with a queue and then implemented it. This gives you a whole new toolset to solve problems with. Background running actors are not just for running on a server for caching. You can run background runner actors for normal programs too if you build your program on a Tokio runtime.
In the next chapter, we will use Redis persistent storage to manage multiple workers and network applications to transfer messages across multiple network applications.
