A very simple cache. It uses timers for the ttl and ets for the storage. No locks are used and there is a fix to prevent thundering herd issues when the cache is warm and pre-emptively refresh the cache (it triggers in low ttl left of item situations). There is also a thundering herd fix for when the cache is cold using a sentinel key and a sleep. Mostly wrapper around ets and kept very simple by using newer apis and recent erlang improvements.
Using property model testing and property tests to verify the cache via propcheck.
