如何在两个JVM实例之间共享内存？ [英] How can I share memory between two JVM instances?

问题描述

我在JVM（Scala）中构建了一个巨大的图形，我想重复使用它，调整算法。我不想每次都从磁盘重装它。有没有办法让它在一个JVM中连接时从另一个JVM开始算法？

I build a huge graph in JVM (Scala) which I want to use repeatedly, tweaking algorithms. I'd rather not reload it each time from disk. Is there a way to have it sit in one JVM while connecting from another, where the algorithms are being developed?

推荐答案

保存你的图形到磁盘，然后使用 MappedByteBuffer <将其映射到内存中/ A>。这两个进程都应该使用相同的内存，它将与页面缓存共享。

Save your graph to disk, then map it into memory with MappedByteBuffer. Both processes should use the same memory, which will be shared with the page cache.
