Tokyo Cabinet

Tokyo Cabinet 是一个DBM的实现。这里的数据库由一系列key-value对的记录构成。key和value均可以是任意长度的字节序列,既能够是二进制也能够是字符串。这里没有数据类型和数据表的概念。

看成为Hash表数据库使用时，每一个key必须是不一样的,所以没法存储两个key相同的值。提供了如下访问方法:提供key,value参数来存储，按 key删除记录，按key来读取记录，另外，遍历key也被支持，虽然顺序是任意的不能被保证。这些方法跟Unix标准的DBM,例如GDBM,NDBM 等等是相同的，可是比它们的性能要好得多（所以能够替代它们)

当按B+树来存储时，拥用相同key的记录也能被存储。像hash表同样的读取，存储，删除函数也都有提供。记录按照用户提供的比较函数来存储。能够采用顺序或倒序的游标来读取每一条记录。依照这个原理，向前的字符串匹配搜 索和整数区间搜索也实现了。另外，B＋树的事务也是可用的。

As for database of fixed-length array, records are stored with unique natural numbers. It is impossible to store two or more records with a key overlaps. Moreover, the length of each record is limited by the specified length. Provided operations are the same as ones of hash database.
对于定长的数组，记录按天然数来标记存储。不能存储key相同的两条或更多记录。另外，每条记录的长度受到限制。读取方法和hash表的同样。

Tokyo Cabinet是用C写的，同时提供c,perl,ruby,java的API。Tokyo Cabinet在提供了POSIX和C99的平台上均可用，它以GNU Lesser Public License协议发布。

Tokyo Tyrant

Tokyo Tyrant 加上 Tokyo Cabinet，构成了一款支持高并发的分布式持久存储系统，对任何原有Memcached客户端来说，能够将Tokyo Tyrant当作是一个Memcached，可是，它的数据是能够持久存储的。这一点，跟新浪的Memcachedb性质同样。

Description: Tokyo Tyrant: network interface to Tokyo Cabinet
 Tokyo Tyrant is a network interface to the DBM Tokyo Cabinet. You might bother
 in the case where multiple processes share the same database or where remote
 processes access the database. Thus, Tokyo Tyrant is provided for concurrent
 and remote connections to Tokyo Cabinet.
 .
 This is the Tokyo Tyrant server package.
