[Codemash] Caching Made "Bootiful"!

Needing more performance from your Java applications? Is latency causing you stress? Repetitive loading of the data in applications, burning CPU time, taxing I/O / disk access? Too many applications caching the same data sets pushing the limits of your data management and application architecture? If so, take a look at JCache! This code-driven session demonstrates how to integrate Hazelcast Distributed Caches into your Spring or Java EE applications. Adding a bunch of annotations to a method can achieve an orders-of-magnitude speed improvement in applications with high-latency.
