Embodiment Construction

[0052] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0053] The invention provides a distributed transaction processing mechanism by simulating the database at the application layer, which can ensure the transaction consistency of the distributed system under the condition of maintaining no intrusion to the business and only requiring the database to support local transactions.

[0054] The distributed transaction processing method provided by the present invention involves three stages: global transaction execution, global transaction submission, and global transaction rollback. Each stage further involves three entity devices, the global transaction server, the transaction branch server and the global transaction man...

Abstract

The invention provides a distributed transaction processing method and device. The method comprises the steps of requesting a global transaction manager to record global transaction information of a transaction, and obtaining a global transaction unique identifier returned by the global transaction manager; executing all transaction branch operations in the global transaction; if any transaction branch of the global transaction fails to be executed, requesting a global transaction manager to roll back the global transaction; and if the local transactions corresponding to the transaction branches of the global transaction are submitted successfully, requesting the global transaction manager to submit the global transaction. According to the distributed transaction processing method and device provided by the invention, the transaction consistency of the distributed system can be ensured under the condition of keeping no invasion to the business and only needing the database to support the local transaction.

Description

technical field [0001] The present invention relates to the technical field of distributed systems, in particular to a distributed transaction processing method and device. Background technique [0002] With the gradual use of distributed technology in bank transaction systems, it is inevitable that a transaction needs to span multiple databases or multiple subsystems (microservices) and guarantee transactions. Since these resources are completely independent physically, it becomes very complicated to ensure the atomicity, consistency, isolation, and persistence control of distributed transactions. [0003] For example, suppose there is a transaction where A transfers 200 yuan to B. The general process is as follows: [0004] 1) Transaction starts [0005] 2) Call the transfer service, A transfers 200 yuan; [0006] 3) Call the transfer-in service, and B transfers 200 yuan; [0007] 4) End of transaction [0008] In a distributed system, transfer-in and transfer-out ser...
