Dan Berindei commented on ISPN-5818:
------------------------------------

This requires some kind of eviction for the null markers, especially when eviction is not enabled for the cache.

When eviction is not enabled and the user is not evicting entries manually, we could skip the cache loader every time. In fact, the application itself could use the {{SKIP_CACHE_LOADER}} flag.

> Today if a user has a cache store and they try to load an entry that doesn't exist we have to take the performance cost of a miss to the back end store.  If the user queries the same key again, we should instead be able to return null right away instead of going to the back end store.
