Distributed transaction processing method, device and system

Abstract

The invention discloses a distributed transaction processing method, device and system, and belongs to the distributed system field; the method comprises the following steps: a business node in the distributed system receives a business request sent by a requestor device, and the business node receiving the business request serves as the main business node; the main business node determines N slave business nodes (besides the main node itself) used for processing business requests; the main business node invokes N slave business nodes to respectively execute corresponding transactions according to the business request and transactions executed by various slave business nodes; the main business node obtains execution results from each slave business node; if a slave business node fails in execution, the main business node can re-invoke the failed slave business node to execute the corresponding transaction according to the preset retry strategy. The method, device and system can effectively solve problems of a 2PC scheme and a TCC scheme.

Description

technical field [0001] The present invention relates to the field of distributed systems, in particular to a distributed transaction processing method, device and system. Background technique [0002] Distributed Transaction (Distributed Transaction) means that the participants of the transaction, the server supporting the transaction, the resource server and the transaction manager are respectively located on different nodes of different distributed systems. Distributed transaction processing involves operations on multiple databases, and the key to distributed transaction processing is to maintain the data consistency of each database. [0003] The two-phase commit protocol (Two-Phase Commit protocol, 2PC) is a common distributed transaction processing scheme. Phase 1 of the 2PC scheme can be called the preparation phase or the voting phase, and phase 2 can be called the submission phase. In the first stage, the transaction manager sends a data operation request to each ...

However, due to the introduction of cancellation processing logic in the TCC scheme, it is necessary to configure cancellation processing logic for all business operations in the software system

If the requirements of the software system are changeable and the business logic is complex, the corresponding cancellation processing logic will also be complex and changeable, resulting in a high implementation cost of the cancellation processing logic, which will bring a large development cost to the software system, and even affect the system Reliability and stability both affect
