Abstract

The invention discloses a distributed transaction processing method and system based on a message queue. The method comprises the steps: numbering sent messages in sequence; writing the sent messagesand the sequence number thereof into a sending log; sending the messages to a server, enabling the server to obtain the sequence number of the messages and compare the sequence number with a sequencenumber stored in a first database, determining the missing starting sequence number and ending sequence number when the two sequence numbers are not continuous, and sending the messages to a message queue when the two sequence numbers are continuous; acquiring missing data from the sending log according to the starting sequence number and the ending sequence number, and sending the missing data tothe server. According to the invention, the sending log and the sequence number stored in the first database which is a non-relational database are utilized to ensure that the message is successfullysent, so the data consistency of the message queue and the service system is ensured, and the development process of the service system is also simplified. The method can be widely applied to the technical field of computers.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a message queue-based distributed transaction processing method and system. Background technique [0002] With the continuous development of the Internet and computer technology, distributed systems are widely used due to their high scalability, high availability, high reliability and high efficiency. With the increasing complexity of IT (Information Technology, information technology) systems, in order to solve the performance and data problems of distributed systems, it is more and more important to build business systems through event sources. MQ (messagequeue, message queue) has The advantages of decoupling and asynchrony are also used on a large scale in event sources. [0003] However, traditional MQ does not support transactions based on relational databases, which leads to consistency problems between MQ and business system data, and also increases the complexity of bu...
