Problems solved by technology

However, in the process of synchronizing global transaction information, it needs to rely on a global logical clock, which is likely to cause a single-point bottleneck problem in the database system, resulting in poor scalability of the database system

Abstract

The invention discloses a transaction processing method and device, computer equipment and a storage medium, and belongs to the technical field of databases. The method comprises the steps of obtaining state information of a target transaction in response to an execution request of the target transaction, verifying a logic life cycle determined based on the state information, executing the targettransaction in response to successful verification of the logic life cycle, and submitting the target transaction in response to successful conflict verification of the target transaction. According to the invention, the transaction processing process does not depend on a certain global logic clock, but depends on the verification of the logic life cycle; the logic life cycle can be adjusted according to a conflict detection result in a transaction execution and verification process; the transaction processing process can be completed by verifying the logic life cycle, so that the single-pointbottleneck problem of the database system is improved, the expansibility of the database system is improved, and the system performance cannot be reduced along with the expansion of the database system.

Description

technical field [0001] The present application relates to the technical field of databases, in particular to a transaction processing method, device, computer equipment and storage medium. Background technique [0002] With the development of database technology, in order to adapt to business scenarios such as big data and cloud computing, distributed database systems have gradually become popular. When performing distributed transaction processing in a distributed database system, decentralized transaction processing technology can be adopted. Decentralized transaction processing technology means that there is no certain node device in the database system to centrally coordinate transactions, but there are multiple node devices in the database system that can be used to act as transaction coordinators. Multiple coordinating node devices jointly process distributed transactions, so it is necessary to ensure the correctness of distributed transactions, usually by communicati...
