Abstract

The embodiment of the invention discloses a data operation optimization method, device and system, equipment and a storage medium. The data operation optimization method comprises the steps: determining a target SQL operation statement in a currently started database transaction, wherein the target SQL operation statement is an SQL operation statement corresponding to a first write operation in the database transaction; and distributing the first SQL operation statement before the target SQL operation statement to a backup database, and distributing the target SQL operation statement and the second SQL operation statement after the target SQL operation statement to a main database. According to the technical scheme provided by the embodiment of the invention, the first SQL operation statement is executed by the backup database, and the database transaction does not change any data, so that the data accessed to the backup database by the client is consistent with the data accessed to the main database, and the main database executes the target SQL operation statement and the second SQL operation statement, so that the separation processing of the read-write operation in the databasetransaction is realized, and the data reading accuracy is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of database processing, and in particular, to an optimization method, device, system, equipment and storage medium for data operation. Background technique [0002] In the database, Structured Query Language (Structured Query Language, SQL) is an operation command set established for the database, including read and write operations; in order to improve the efficiency of reading and writing data in the database, usually through the main database and backup The database uses data read and write separation to read and write data in the database. [0003] At present, when the client executes a database transaction, it first judges the type of operation that exists in the SQL operation statement corresponding to the database transaction. If there is only a read operation, the SQL operation statement is executed through the backup database; if there is a write operation, it is executed through the...
