Java 中的 B+Tree 磁盘实现 [英] B+Tree on-disk implementation in Java

问题描述

有谁知道在哪里可以找到磁盘上的 B+Tree 实现?我前后浏览了谷歌，不幸的是我找不到任何明智的东西.其他线程建议可能从 sqlite、sqljet 或 bdb 中获取树，但这些树嵌套在整个数据库中，您不能真正仅仅"过滤掉 B+树.我真的只是在寻找一个磁盘上的 B+树......没有任何花哨的东西.

Does anyone know where to find a B+Tree on-disk implementation? I went through google forward and backward and unfortunately I couldn't find anything sensible. Other threads have suggested to maybe take the tree from sqlite, sqljet or bdb but these trees are nested in the whole database and you can't really "just" filter out the B+Tree. I'm really looking for only a on-disk B+Tree... without any fancy things around.

推荐答案

有一个受 GDBM 启发的 Java 持久化引擎:MapDB

There is a GDBM-inspired Java persistence engine: MapDB
