Cache Invalidation
A classic problem and set of mechanisms in distributed systems for handling the expiration of cached data. It involves ensuring that cached copies are invalidated or updated in a timely manner when the underlying source data changes. Common solutions include asynchronous invalidation via message queues and version-vector-based conflict detection.

The proactive invalidation approach essentially transforms the memory system consistency problem into the classic cache invalidation problem, and mature patterns from the distributed systems domain—such as asynchronous invalidation based on message queues and conflict detection based on version vectors—can be leveraged.
Cache invalidation is a classic hard problem in computer science, and common strategies include time-based TTL, event-driven active invalidation, and synchronous updates on write.
