Out-of-process (client/server) caching provides the option of using dedicated cache servers. This benefit is most directly realized by the Local, Replicated, Optimistic and Near Cache implementations. In-process caching provides the highest level of raw performance, since objects are managed within the local JVM. Several different near-cache strategies are available and offer a trade-off between performance and synchronization guarantees. Near Cache-Provides the performance of local caching with the scalability of distributed caching. The distribution algorithm minimizes network traffic and avoids service pauses by incrementally shifting data. Data is automatically, dynamically and transparently partitioned across nodes. Replicated Cache-Perfect for small, read-heavy caches.ĭistributed Cache-True linear scalability for both read and write access. Local Cache-Local on-heap caching for non-clustered caching.
