Idea for add some fallback feature for custom cache

[BruceRodrigues]

Hey all,

Just want to give some feedback/idea about the new incoming custom cache provider feature.
I was trying to build a custom cache to add some initial data for every page. That way, if for any reason an API request doesn't work I can fill my components/pages with something, and also don't need to be always worrying about null checks. But to do that I needed to build some fallback feature, so if I make a request using the key /api/example/1 I can fallback to /api/example/dummy.

I think it would be awesome if we had something like that out-of-the-box.
Also, since you're making cache more flexible, I think it would be a good idea if we had an unserializable function to get the key's original value.

Let me know what you guys think!

@BruceRodrigues Thanks for these great feedback! Do you have any usage examples for unserializable cases you're trying to work with? That would be very helpful for us to improve the cache API
