Expiring data
When data is cached, we can configure the data to expire from the cache after a specified amount of time. Some caching systems allow you to configure a system-wide expiration policy in addition to an expiration policy for an individual cached item. The expiration is typically specified as an absolute value (for example, 1 day).
