Caching
Alice's Adventures in Cache Invalidation
A curious journey through expiry, consistency, and other impossible things before breakfast
If a value changes in the forest and the edge cache does not hear it, several users will.
Alice follows a stale response into a world where time-to-live is advisory, distributed state is argumentative, and every performance improvement has a small label reading 'DRINK ME'. This volume explains cache keys, eviction policies, invalidation strategies, and the social perils of believing a dashboard that was refreshed yesterday.
