Terracotta BigMemory是否有任何开源替代方案?

Is there any open-source alternative for Terracotta BigMemory?

实际上，我什至没有找到任何商业选择.我对纯Java解决方案感兴趣，该解决方案无需任何JNI和C支持的解决方案即可在JVM内运行.

Actually I didn't even manage to find any commercial alternative. I'm interested in pure Java solution which will work inside JVM without any JNI and C-backed solution.

推荐答案

有一个非常好的缓存解决方案，名为 MapDB (以前是JDBM4).它支持HashMap和TreeMap，但仅是嵌入式应用程序.它还支持基于持久性文件的缓存.

There is a very good cache solution named MapDB(JDBM4 formerly). It supports HashMap and TreeMap But it is only application embedded. It also support persistent file based cache.

堆外缓存示例:

DB db = DBMaker.newDirectMemoryDB().make(); ConcurrentNavigableMap<Integer, String> map = db.getTreeMap("MyCache");

或基于持久性文件的缓存:

Or persistent file based cache:

DB db = DBMaker.newFileDB(new File("/home/collection.db")).closeOnJvmShutdown().make(); ConcurrentNavigableMap<Integer,String> map = db.getTreeMap("MyCache");
