这是 kyoko cabinet C 库的Lua语言绑定的API接口。



kyoko cabinet 是一个管理数据库的库。该数据库是一个单一的数据文件，每个记录为关键字和值。每个关键字和值是可变长度的字节序。二进制数据和字符串都可作为关键字或值。每个关键字必须唯一。没有数据表和数据类型的概念。记录以哈希表和b树组织。-Kyoto 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. Each key must be unique within a database. There is neither concept of data tables nor data types. Records are organized in hash table or B+ tree.



The following access methods are provided to the database: storing a record with a key and a value, deleting a record by a key, retrieving a record by a key. Moreover, traversal access to every key are provided. These access methods are similar to ones of the original DBM (and its followers: NDBM and GDBM) library defined in the UNIX standard. Kyoto Cabinet is an alternative for the DBM because of its higher performance.



Each operation of the hash database has the time complexity of "O(1)". Therefore, in theory, the performance is constant regardless of t
