Distributed transaction processing method and system

Abstract

A distributed transaction handling method, comprising: a primary service system dividing a distributed transaction into multiple sub-transactions, recording corresponding operation states in a main transaction table, and sending to corresponding secondary service systems instructions to execute the sub-transactions, respectively; and the secondary service systems performing, according to the instructions of executing the sub-transactions, corresponding operations in preliminary tables of the sub-transactions, and recording corresponding operation states in corresponding sub-transaction tables.

Description

technical field [0001] The invention relates to the field of computer processing, in particular to a distributed transaction processing method and system. Background technique [0002] Transaction (Transaction) is a reliable and independent unit of work composed of a set of operations, in which all operations either succeed or fail. Transactions have four basic characteristics: atomicity, consistency, isolation, and durability, also referred to as the ACID characteristics of transactions. In the era of microservices, after a large number of business splits, the problem of data consistency in distributed transactions follows, especially the distributed transactions between different systems involving transactions. In order to ensure the data consistency of distributed transactions, the operation status of each transaction or sub-transaction is recorded through the transaction table. The management of the traditional transaction table is to uniformly manage the operation stat...

Problems solved by technology

In order to ensure the data consistency of distributed transactions, the operation status of each transaction or sub-transaction is recorded through the transaction table. The management of the traditional transaction table is to uniformly manage the operation status of each transaction through a separate service system, so that each business All systems need to establish a network connection with the service system, which not only consumes network traffic, but also because each business system needs to interact with the service system, all operation records are recorded in the same transaction table, which not only increases the burden on the transaction table, but also It leads to low operating efficiency, and if the service system fails, it will cause the entire business system to be paralyzed, that is, there is a single point of failure
