Data storage method, retrieval method based on key-value database and corresponding device

Abstract

Embodiments of the present application provide a data storage method and retrieval method based on a key-value database and corresponding devices. The data storage method based on the key-value database comprises: obtaining key-value pair data to be stored, the key-value pair data comprising an original key and a value; the original key is of a string type; the original key of the string type is converted into an index key of an integer type of a specified byte length using a conversion rule; the value of the key-value pair data is stored in a value storage area of the key-value database, and an offset and a length of the value in the value storage area are recorded; a directory item corresponding to the value is generated according to the index key, the offset and the length, and the directory item is stored in a key storage area of the key-value database. The original key of the string type is converted into the index key of the integer type of the specified byte length, the key storage area of the key-value database is facilitated to be regular, and the occupied space of the key storage area can be reduced.
