I'm seeing some discrepancy between documentation [1] and API docs [2]. In documentation the keySet() and other methods are listed as limited to local cache. In API docs they are only listed as prohibitively expensive but from the wording they seem NOT limited to local cache.

I think these both docs need to be put in sync by somebody that knows how it actually works.
