Hazelcast JCache

This chapter describes the basics of JCache, the standardized Java caching layer API. The JCache caching API is specified by the Java Community Process (JCP) as Java Specification Request (JSR) 107.

Caching keeps data in memory that either are slow to calculate/process or originate from another underlying backend system. Caching is used to prevent additional request round trips for frequently used data. In both cases, caching can be used to gain performance or decrease application latencies.
