Abstract

The invention relates to the technical field of computer data storage, in particular to a method, device and system for writing data pairs in LevelDB databases. The method provided herein comprises: configuring multiple LevelDB databases corresponding to multiple message queues; writing data pairs into one message queue; writing the data pairs of the message queue into the LevelDB database corresponding to the message queue, wherein before configuring the multiple databases corresponding to the multiple message queues, steps also are included which include: creating multiple catalogues, and configuring multiple catalogues corresponding to the multiple LevelDB databases, and wherein writing the data pairs into one message queue includes: allocating the data pairs among the multiple message queues through Hash algorithm, and determining the message queue which the data pairs are to be written in. The problem that writing performance of LevelDB databases under high stress is low is solved, and the writing performance of LevelDB databases is improved.

Description

technical field [0001] The invention relates to the technical field of computer data storage, in particular to a method, device and system for writing data pairs in a leveldb database. Background technique [0002] The leveldb database is a key-value storage engine library open sourced by Google. The data pairs mentioned in this application document are key-value pairs. When the leveldb database stores data, it is stored in order according to the recorded key values, that is to say Adjacent key values ​​are stored sequentially in the storage file, and the application can customize the key size comparison function, and the leveldb database will store these records in sequence according to the user-defined comparison function. [0003] In the field of data storage, there are many application scenarios of the leveldb database, and there will be some problems with low performance in the application process of the leveldb database: for example, in a large-scale write scenario, th...
