Abstract

The invention relates to a distributed transaction message subscription method, an electronic device and a readable storage medium. The method comprises the following steps of: obtaining a primary database log sent by a primary database and a secondary database log sent by a secondary database; and analyzing the obtained primary database log and secondary database log into messages and forming a message queue according to the analyzed messages; informing a business system which pre-subscribes messages of the messages in the message queue, wherein the primary database log and the secondary database log are database logs which are generated through carrying out corresponding data operations on the primary database and the secondary database by the business system according to user instructions. According to the method, database logs can be analyzed into messages in real time and the messages are sent to business systems which pre-subscribes messages, so that low time delay of distributedtransaction processing can be ensured through the message subscription manner and then the availability and performance of the systems are improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a message subscription method for distributed transactions, an electronic device and a readable storage medium. Background technique [0002] In business development, many scenarios need to solve the problem of data consistency in distributed transactions. The cause of data inconsistency is generally caused by delay, so the influence of this delay should be eliminated. The existing solutions are all to avoid the CUD operation from the master database, that is, after the master and slave databases are synchronized, the write request on the master database will be returned. This approach will greatly reduce the availability and performance of the system. Contents of the invention [0003] The purpose of the present invention is to provide a message subscription method for distributed transactions, an electronic device and a readable storage medium, aiming at improving...
