Scoping could be useful for use cases where creating a cache per scope is too expensive. E.g., I want to cache a person's name, address and photograph.

cache.withAffinityKey("k1").put("country", "UK");<br>
<br>
cache.withAffinityKey("k2").put("name", "Sanne");<br>
cache.withAffinityKey("k2").put("country", "IT");<br>
<br>
will be allowed and the two will not overwrite each other, *but* you cannot retrieve stuff by simply doing:<br>
<br>
cache.get("name") anymore. You would have to do:<br>
<br>
cache.withAffinityKey("k1").get("name"). Simply doing a cache.get("name") will return a null.<br>
<br>
What do people prefer?<br>
