Description of the illustration near-cache.jpg

The image shows four boxes that each represent a JVM in a Coherence cluster. Each JVM contains an application box and a near cache box. Each near cache box contains: a logical cache box, a local cache box, and a partitioned cache box that contains a logical cache box together with a primary storage box and a backup box. Data is labeled A through D and is located in all the logical caches of each JVM. The application in JVM one is performing two get operations for data B and C. The application in JVM two is performing a get operation for data B. The application in JVM three is performing two get operations for data A and D. The get operations are performed on the logical cache of the respective JVMs. However, for data B and D, the data is first loaded into the local cache from primary storage.
