Introducing caching

In the previous section, we talked about databases and wiring one up to our user store example. However, in applications, a database will often be the main performance bottleneck in the technology stack. The queries we used in the previous section were quite simple, but as an application grows, so does the complexity of a typical database query. Query complexity, as well as a database growing in size will increase the length of time it takes for a single query to run, making for a poor experience for users of our application.
