Earlier in this series, you learned that a cache on disk has a number of benefits. It persists the cache across launches and it can be used to seed a cache in memory. Even though modern devices have plenty of disk space, we need to be mindful of the space the cache on disk takes up on the user's device. Applications like Twitter and Instagram fetch hundreds if not thousands of images. Even if those images are optimized and small in size, the cache on disk can grow quickly, taking up a non-trivial amount of space on the user's device. In this episode, we add the ability to limit the size of the cache on disk, similar to how the image service limits the size of the cache in memory.
