[FEATURE] Expire entire cache about fusioncache HOT 3 CLOSED

Hi @giulianob , I'm not sure I understand the scenario you have in mind.

May I ask you to try to explain it a little bit more? Maybe with a concrete example, a step-by-step list like:

• I do this
• and this happens
• then this happens
• etc

Thanks!

The use case is as following:

• There is a custom backplane implementation
• When an item changes, the backplane pushes a message to all of the connected clients
• When a client receives backplane message, the item should be expired from the cache (not removed)
• If the connection between the client and backplane is disconnected, all items in the cache should be marked as expired (because the client may have missed item change messages)

Hi @giulianob , sorry for the delay but somehow I lost track of this issue.

Anyway, currently there's no ready made solution to cover this particular scenario, and in general it's not possible to completely clear a cache, for various reasons.

If you want to learn more about why this is the case and what other people do think, I suggest to take a look at the issue currently unfolding about the new distributed cache effort going on for .net 9 , it's ful of interesting experiences and ideas.

I'm closing this since, in general, a Clear() method cannot be supported, but if something new comes up I'll gladly reopen it.
