 Without some extra care what can happen is that data would not be saved in the distributed cache or other nodes may not be notified of changes: this would result in out-of-sync issues.

 Tagging is an incredibly powerful feature: cache entries can be tagged with one or more tags, and later they can be evicted all at once by just calling `RemoveByTag("my-tag")`.
 
-The overall [design](https://github.com/ZiggyCreatures/FusionCache/issues/319) used to achieve this is such that, even when working against a massive cache with millions of entries, will not incur in any upfront cost (yes, even a distributed L2 like a Redis gigantic instance).

 Thanks to the design used for the Tagging feature (see above), FusionCache also supports a proper `Clear()` mechanism for the entire cache.
 
-Yes, yes: the abiltiy to clear seems like an easy one but when we consider things like shared caches, cache key prefix and all the other features... it's definitely not an easy feat. But yeah, it just works.
