Distributed transaction processing method, device, system and electronic equipment

Abstract

The invention provides a distributed transaction processing method, device, system and electronic equipment. Wherein, the method includes: the central server responds to the transaction initiation request of the first transaction server, assigning global transaction information to the transaction corresponding to the transaction initiation request; distributing the global transaction information to the second transaction server participating in the transaction through the first transaction server, Make the second transaction server feed back the to-do item information corresponding to the transaction according to the global transaction information; and store the to-do item information corresponding to the global transaction information to the storage server; At the same time, the to-be-operated item information corresponding to the global transaction information in the storage server is processed, thereby realizing the consistency and concurrency of data in the process of distributed transaction processing, and improving the processing efficiency of distributed transactions.

Description

Technical field [0001] The present invention relates to network technologies, and particularly relates to distributed transaction processing method, apparatus, systems and electronic devices. Background technique [0002] With the continuous development and changes in user demand for Internet, business applications and more complex, particularly in relation to the financial industry's business affairs, it uses a distributed architecture to achieve efficient service. In a distributed architecture, with a trading business you may need to be accessed across multiple databases, such as read operations and / or write operation, in order to ensure consistency of data across multiple database access, mostly using distributed transactions in financial transactions deal with. [0003] In practice, a distributed transaction has a final consistency, for example, a distributed transaction data generated by the A modification is B, then, during the execution of a distributed transaction, the ...

Problems solved by technology

[0004] The current distributed transactions are divided into strong consistency and weak consistency; among them, strong consistency can ensure the strong consistency of data under distributed transactions, but this method needs to keep the transaction for a long time, which may cause problems such as deadlock , the performance is relatively low, and the usage scenarios are limited. Therefore, most of the existing distributed transactions adopt weak consistency. Although this method can ensure the final data consistency of the transaction, data dirty reading may occur, that is, a distributed transaction can read The data being accessed by unfinished distributed transactions leads to the inability to guarantee data consistency and concurrency performance during distributed transaction processing, thus affecting the processing efficiency of distributed transactions
