用Java编写的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B + Tree磁盘实现？我经历了谷歌向前和向后，不幸的是我找不到任何明智的东西。其他线程建议可以从sqlite，sqljet或bdb中获取树，但这些树嵌套在整个数据库中，你不能真正只过滤掉B + Tree。
我真的只是在寻找一个磁盘上的B +树...没有任何奇特的东西。

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持久性引擎： MapDB

There is a GDBM-inspired Java persistence engine: MapDB
