Provide typed LRU cache for field values

Sometimes we store something heavy in stored fields that need additional complex conversion.
Maybe we can provide an implementation for Database that would allow us to cache some work done by some Function<Buffer, T> and return T immediately.

It looks like an independent component.
Can you please provide a clarifying example or use case?

Sometimes deserialization of a field is very expensive on a high-load service and it is handy to have deserialized values of the document being cached for hot documents (or even all of them).
