How to speed up your application using JCache
summary
JCache is a Java standard (finalized 2014) with six mainstream implementations (Ehcache, Hazelcast, Coherence, Infinispan, GridGain/Ignite, Caffeine) and a simple API that adds entry processor semantics and stats. Distributed caches cut database latency (databases ~3–10 ms) to microseconds (Hazelcast reports ~160 µs over network, ~70 µs on 10/40G) and can yield up to 90% offload from databases. Large deployments are proven (Hazelcast tested 600 nodes / 7,000 cores, 500 GB per node with a high-density memory store; hot-restart SSD at ~300k writes/sec; 100 GB restart ~70s).
