Abstract

The application relates to a database processing method, device, computer equipment and storage medium. The method includes: the server receives the database node operation instruction, determines the target hash slot according to the identification of the target node in the database node operation instruction, and allocates a new database for the target hash slot according to the distribution of the hash slots on each database node node, and update the correspondence between database nodes, hash slots, and hash value ranges. In this method, by constructing the hash slot corresponding to the database node between the database node and the hash value range, the indirect mapping relationship between the database node and the hash value range is realized, so that the adjustment of the database node , it will not directly affect the hash value range, avoiding the failure of the hash value range. Based on the mapping relationship structure of database node-hash slot-hash value range, the dynamic adjustment of database nodes is realized, which improves the Expansion efficiency of database nodes.

Description

technical field [0001] The present application relates to the technical field of databases, and in particular, to a database processing method, apparatus, computer equipment and storage medium. Background technique [0002] With the increase of the amount of data in the database, the problem of database data pressure is solved by the database sub-database sub-table technology. Database sub-database sub-table technology refers to the construction of multiple database nodes in the database, and the data originally stored in one database is stored on multiple database nodes in blocks. Each database node corresponds to multiple database tables. Nodes, multiple database tables to process data to solve the problem of data pressure. [0003] Generally, database sub-database sub-table is implemented by hash (hash) mapping, that is, a database node maps multiple hash values, and each hash value corresponds to the data in the database table one-to-one, realizing database nodes, hash ...
