Distributed transaction processing method and device and storage medium

Abstract

The embodiment of the invention provides a distributed transaction processing method and device and a storage medium. In some embodiments of the invention, the method comprises the steps of receiving a distributed transaction starting request sent by a transaction request end by distributed transaction processing equipment; according to the starting request, obtaining an execution sequence of a plurality of pre-configured sub-processes; according to the execution sequence of the plurality of sub-processes, executing the plurality of sub-processes in sequence; adding a condition for judging whether a retry is met after execution of a target sub-process fails, executing retry operation on the target sub-process under the condition of meeting the retry condition, adding a condition for judging whether a rollback condition is met or not after execution of the sub-process fails, and executing retry operation on the target sub-process under the condition of meeting the rollback condition, reversely executing the rollback operation of all the executed sub-processes from the target sub-process, so that the probability of successful execution of the distributed transaction is increased, the probability of data inconsistency caused by instability of the distributed system is reduced, the self-healing capability of the distributed system in a fault scene is improved, and the execution efficiency of the transaction is improved.

Description

technical field [0001] The present application relates to technologies in the field of distributed computing, and in particular to a distributed transaction processing method, device and storage medium. Background technique [0002] In the distributed system architecture, the entire business process is jointly completed by multiple business nodes providing multiple services, and a business logic often needs to operate data on multiple services. In order to ensure the data consistency of multiple services, it is usually necessary to introduce a distributed transaction mechanism for processing. Each transaction includes different business operations on multiple nodes, and the execution results of the transaction can only succeed or fail. [0003] At present, based on the transaction model of Saga theory, a long transaction T that executes multiple steps is split into multiple sub-transactions: t1, t2, ..., tm-1, tm, tm+1, ..., tn; at the same time, define the rollback logic o...

AI Technical Summary

Problems solved by technology

[0004] Based on the transaction model of Saga theory, for any sub-transaction, after the execution of the sub-transaction fails, it needs to perform a rollback operation on the sub-transaction. This kind of processing flow is cumbersome and not simplified enough, which affects the execution efficiency of the transaction.
