关于Tokyo Cabinet你知道多少
最近在研究队列，了解了一些开源的队列，包括httpSQS, RabbitMQ,ActiveMQ
关于Tokyo Cabinet你知道多少,下面我翻译的一段文章，原文和翻译均贴出。 有些翻译不是很到位。有待提高！
## 译文如下
顺便提下，你了解Kyoto Cabinet吗？实际上，它是一个比Tokyo Cabinet 还要强大和方便的开发包。经过这样长的时间，Kyoto Cabinet 在很多方面都超过Tokyo Cabinet。我强烈建议你使用Kyoto Cabinet 。
概述
Tokyo Cabinet 是一个管理数据库的常规开发包。数据库是一个包含记录的简单数据文件，每个记录是一个key-value对，每个键和值都是可变长度的字节序列。没有数据表和数据类型的概念。记录都是使用hash table, B+ tree或者固定长度的数组组织的。
Tokyo Cabinet是基于以下目的作为GDBM and QDBM的继承者而开发的。它们已经被实现并且Tokyo Cabinet正在替代传统的DBM产品。
- 提高了空间效率：更小的数据库文件
- 提高了时间效率：更快的处理速度
- 提供了并行：在多线程环境下具有更高的性能
- 提高了可用性：简单化的API
- 提高了健壮性：即使在毁灭性的情况下数据库文件也不会被损坏
- 支持64位操作系统的架构：庞大的内存空间和数据库文件是可用的
Tokyo Cabinet是使用C语言编写的，并且提供 C, Perl, Ruby, Java, 和 Lua的API 。Tokyo Cabinet在遵循C99 和 POSIX协议的API的平台是可用的。Tokyo Cabinet是一个免费的软件许可证，遵循GNU通用公共许可证。

BTW, do you know Kyoto Cabinet? Actually, it is more powerful and convenient library than Tokyo Cabinet. At this distance of time, Kyoto Cabinet surpasses Tokyo Cabinet in every aspects. I strongly recommend you to use Kyoto Cabinet.
Overview
Tokyo Cabinet is a library of routines for managing a database. The database is a simple data file containing records, each is a pair of a key and a value. Every key and value is serial bytes with variable length. Both binary data and character string can be used as a key and a value. There is neither concept of data tables nor data types. Records are organized in hash table, B+ tree, or fixed-length array.
Tokyo Cabinet is developed as the successor of GDBM and QDBM on the following purposes. They are achieved and Tokyo Cabinet replaces conventional DBM products.
improves space efficiency : smaller size of database file. improves time efficiency : faster processing speed. improves parallelism : higher performance in multi-thread environment. improves usability : simplified API. improves robustness : database file is not corrupted even under catastrophic situation. supports 64-bit architecture : enormous memory space and database file are available. Tokyo Cabinet is written in the C language, and provided as API of C, Perl, Ruby, Java, and Lua. Tokyo Cabinet is available on platforms which have API conforming to C99 and POSIX.
