Best cache framework for Java
提问by Rodrigo Asensio
I need to implement a cache solution in java for a cluster of 9 servers with web applications. I saw apache JCS, seems old, do you know another open source solution?
我需要在 Java 中为具有 Web 应用程序的 9 个服务器集群实现缓存解决方案。看了apache JCS，好像老了，你知道另一个开源解决方案吗？

You can try to look at Terracottaframework Or you can use distributed Ehcache
你可以试试看Terracotta框架 或者你可以使用分布式Ehcache

I think in order to use distributed EhCache you need a commercial Terracotta license.
我认为为了使用分布式 EhCache，您需要一个商业 Terracotta 许可证。
Another alternative would be memCached (see: http://memcached.org) which does not require commercial license and its widely used by high traffic web sites like YouTube, LiveJournal, Flikr, Wikipedia, etc...
另一种选择是 memCached（参见：http: //memcached.org），它不需要商业许可，并且被 YouTube、LiveJournal、Flikr、维基百科等高流量网站广泛使用......

Correction, you do not need a commercial license to do a distributed cache with Terracotta's Ehcache. Ehcache lets you do just a few nodes in a cluster, one of them being the TSA if I remember correctly.
Memcache is purely a caching layer that isn't persistent to disk, Terracotta's Ehcache is.
更正，您不需要商业许可即可使用 Terracotta 的 Ehcache 进行分布式缓存。Ehcache 允许你在集群中只做几个节点，如果我没记错的话，其中一个是 TSA。
Memcache 纯粹是一个缓存层，不是持久到磁盘的，Terracotta 的 Ehcache 是。
As for when it comes to Java, Terracotta's Ehcache is off the jave heap, this lets you have as big of a cache as you want depending on the amount of memory your server has. They're working with single JVMs that have 4TB heap sizes w/ no garbage collection at all. Memcache doesn't have this off heap feature at all.
至于 Java，Terracotta 的 Ehcache 不在 jave 堆中，这让您可以根据服务器拥有的内存量拥有尽可能大的缓存。他们正在使用具有 4TB 堆大小的单个 JVM，而根本没有垃圾收集。Memcache 根本没有这个堆外特性。
Downside, if your app isn't Java, Terracotta will be a lot of work- Terracotta is primarily Java based.
不利的一面是，如果您的应用程序不是 Java，Terracotta 将需要大量工作——Terracotta 主要是基于 Java 的。
I just met these guys at JavaOne this last week, so I got a lot of good information from them.
上周我刚刚在 JavaOne 遇到了这些人，所以我从他们那里得到了很多很好的信息。
