diskcache has a peekitem method that allows you to lookup the expire_time of a cached item without changing it.  I recently used this to implement debounce for fastapi background tasks with multiple workers running.  since all the workers I care about are on the same machine, but running in different processes diskcache was a great option.  All workers have access to the same disk, but not the same variables in memory.
