An application is hosted in Elastic Beanstalk with an ElastiCache cluster that acts as a database cache layer for accessing its data in DynamoDB. It is currently configured to write the data to the cache only if there is a cache miss, which causes the data in the cache to become stale. A developer is instructed to ensure that the data in the cache is always current and to minimize wasted space in the cluster by automatically deleting the data that are never read. What is the BEST way to implement this to satisfy the given requirement?
