Problems solved by technology

This is because most analytical databases use columnar storage and compression, and in-situ updates are not easy to implement; in addition, in the business scenarios of analytical databases, the concurrency requirements for writing transactions are not high

Abstract

The embodiment of the invention discloses a data operation method and device, electronic equipment and a storage medium. The method comprises the steps of receiving a data operation request; obtaining a current operation transaction identifier corresponding to the data operation request; operating a database according to the current operation transaction identifier and the associated information, wherein the associated information comprises a corresponding relationship among a historical operation type, a historical operation transaction identifier and a historical operation position identifier of the historical operation, and the historical operation is executed database operation. According to the technical scheme, multi-version concurrency control of the database can be achieved, the data can be persistently written into the database in the data writing process, and the situation that only the modified data can be written into the cache does not exist.

Description

technical field [0001] The present disclosure relates to the technical field of computer technology, and in particular to a data operation method, device, electronic equipment and storage medium. Background technique [0002] In databases, transactional database multi-version concurrency control is usually implemented based on rows, and analytical databases are implemented based on greater granularity. This is because most analytical databases use columnar storage and compression, and in-situ updates are not easy to implement. In addition, in the business scenarios of analytical databases, the concurrency requirements for writing transactions are not high. Therefore, with the development of databases, hybrid business scenarios continue to emerge, and the requirements for analytical database transaction capabilities are getting higher and higher. Therefore, how to implement a row-level multi-version concurrency control solution for columnar storage databases is one of the pr...
