Terracotta

Terracotta到底是什么呢？官方是这样定义的：Open Terracotta is an enterprise-class, open-source, JVM-level clustering solution. JVM-level clustering simplifies enterprise Java by enabling applications to be deployed on multiple JVMs, yet interact with each other as if they were running on the same JVM. Terracotta extends the Java Memory Model of a single JVM to include a cluster of virtual machines such that threads on one virtual machine can interact with threads on another virtual machine as if they were all on the same virtual machine with an unlimited amount of heap.
