Transaction reversal method and device, service system, equipment and storage medium

Abstract

The invention relates to the technical field of data processing, in particular to a transaction reversal method and device, a service system, equipment and a storage medium, the method is applied to a transaction management platform, the transaction management platform is in communication connection with at least one service node cluster, and the method comprises the following steps: determining a to-be-processed first reversal transaction flow; obtaining a service identifier and a flow identifier corresponding to the first reversal transaction flow, the service identifier being used for identifying a service node cluster generating the first reversal transaction flow, and the flow identifier being used for identifying the first reversal transaction flow; and sending a reversal request to a service node cluster corresponding to the service identifier, wherein the reversal request comprises the flow identifier, and the reversal request is used for indicating the service node cluster to carry out reversal processing on the first reversal transaction flow. According to the transaction reversal method provided by the embodiment of the invention, the success rate of transaction reversal is improved, and the timeliness of transaction reversal is also considered.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a transaction redaction method, device, service system, equipment and storage medium. Background technique [0002] In the face of the new development trend of Internet finance, the traditional single IT architecture is increasingly exposed to the shortcomings of inefficiency, which has given birth to the development of distributed technology. By transforming the single application service into a distributed service model, the pressure on the service system due to rapid business growth can be reduced. [0003] According to the CAP theory, distributed systems have three characteristics, namely Consistency (C for short), Availability (A for short) and Partition Tolerance (P for short). Any distributed system can only Satisfy two of the three characteristics of data consistency, availability, and partition tolerance. Usually, in the process of designing a distribut...

[0004] Among them, the post-processing is to send the abnormal transaction to the record table of the failed transaction through the message queue, and roll back the transaction through manual processing after the event. This method usually takes several hours or the next day to complete, and the real-time performance is poor.

Asynchronous flushing failures are sometimes caused by special reasons within a certain period of time. In this way, even if retries are repeated many times, it will fail. As the number of flushing failures increases, polling and judgment will consume too much system resources. Therefore, in order To ensure the normal operation of the system, usually no more retries will be made after asynchronous flushing reaches a certain number of times, so that the success rate of asynchronous flushing is not high, and it is difficult to meet the needs of financial distributed service systems
