Tokyo Cabinet

Tokyo Cabinet 是一個DBM的實現。這裏的數據庫由一系列key-value對的記錄構成。key和value均可以是任意長度的字節序列,既能夠是二進制也能夠是字符串。這裏沒有數據類型和數據表的概念。

看成爲Hash表數據庫使用時，每一個key必須是不一樣的,所以沒法存儲兩個key相同的值。提供瞭如下訪問方法:提供key,value參數來存儲，按 key刪除記錄，按key來讀取記錄，另外，遍歷key也被支持，雖然順序是任意的不能被保證。這些方法跟Unix標準的DBM,例如GDBM,NDBM 等等是相同的，可是比它們的性能要好得多（所以能夠替代它們)

當按B+樹來存儲時，擁用相同key的記錄也能被存儲。像hash表同樣的讀取，存儲，刪除函數也都有提供。記錄按照用戶提供的比較函數來存儲。能夠採用順序或倒序的遊標來讀取每一條記錄。依照這個原理，向前的字符串匹配搜 索和整數區間搜索也實現了。另外，B＋樹的事務也是可用的。

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.
對於定長的數組，記錄按天然數來標記存儲。不能存儲key相同的兩條或更多記錄。另外，每條記錄的長度受到限制。讀取方法和hash表的同樣。

Tokyo Cabinet是用C寫的，同時提供c,perl,ruby,java的API。Tokyo Cabinet在提供了POSIX和C99的平臺上均可用，它以GNU Lesser Public License協議發佈。

Tokyo Tyrant

Tokyo Tyrant 加上 Tokyo Cabinet，構成了一款支持高併發的分佈式持久存儲系統，對任何原有Memcached客戶端來說，能夠將Tokyo Tyrant當作是一個Memcached，可是，它的數據是能夠持久存儲的。這一點，跟新浪的Memcachedb性質同樣。

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.
