I've been trying to wrap my head around core.cache, and it seems to me that the suggest use in the documentation, i.e.
will result in a Cache Stampede since (retrieve-data key) might be called multiple times if swap! retries due to compare-and-swap misses. Unfortunately I don't have a suggestion on how this could be fixed.

Released/addressed in 0.8.0 through 0.8.2 (0.8.0 and 0.8.1 both had bugs in the wrapped API that are fixed in 0.8.2).

Addition of clojure.core.cache.wrapped with comparable API plus lookup-or-miss to provide stampede-free version of this functionality for caches wrapped in atoms.
