Inﬁnispan 是个开源的数据网格平台。它公开了一个简单的数据结构（一个Cache）来存储对象。虽然可以在本地模式下运行Inﬁnspan，但其真正的价值在于分布式，在这种模式下，Inﬁnispan可以将集群缓存起来并公开大容量的堆内存。这可比简单的复制强大的多，因为它会为每个结点分配固定数量的副本——服务器故障的一种恢复手段——同时还提升了可伸缩性，这是由于存储每个结点所需的工作量是与集群大小息息相关的。

Infinispan 7.2.0.Final 发布，数据网格平台

Inﬁnispan 提供了一种简单的机制来利用大容量的堆内存。如果对每个结点维护一个拷贝，假如集群当中有100个结点，每个结点分配2GB的堆内存，那么网格中的任何实例都能使用多达100GB的空间，这可都是内存，显然速度会非常快。同时Inﬁnispan还兼容于JTA，这样它就能很好地处理事务了。我们还有一个超级强大的异步API，它可以保证同步的网络调用以及异步调用的并行性及可伸缩性。比方说：Future f = cache.putAsync(k, v) 可以阻塞线程，再调用f.get()可以让网络调用继续进行或是忽略掉f。更为重要的是，线程还可以做别的事情，这一点非常有用。然后再回来通过调用 f.get()来检查该网络调用是否能继续进行。可以将其看作是NIO与传统的阻塞性IO之间的关系。

Inﬁnispan公开了一个 CacheStore接口和几个高性能的实现，包括JDBC CacheStores、基于文件系统的CacheStores以及Amazon S3 CacheStores等等。CacheStores可用作“温启动（warm starts）”或是确保网格中的数据在重启后依然可用，同时在内存耗尽时还能将数据写到磁盘上。
