 ## Implementation and Configuration
+
+Implement the `CacheLoader` interface to handle cache read misses.
+A get operation that causes a miss invokes 
+the `CacheLoader.load` method.
+This method is expected to return the value associated with the
+cache miss.
+Therefore, the implementation must acquire the value.
+Upon return from the `CacheLoader.load` method,
+the `get` operation places the key/value into the region
+before it completes by returning the value.
+See details about cache loaders at
+[Implement a Data Loader](../developing/outside_data_sources/implementing_data_loaders.html).
