Question 4

An application frequently requests data (from s Coherence cache configured with a cache loader) that may not be available in the underlying data source. The cost of looking up data via the cache loader is expensive in terms of time and resources.

A. Configure a "cache-miss-scheme" on the appropriate cache.

B. Modify the cache loader to maintain a "map" of entries not found, and consult this map before attempting to load an entry from the external source.
