Distributed transaction processing method, device and system and electronic equipment

Abstract

The invention provides a distributed transaction processing method, device and system and electronic equipment. The method comprises the following steps: a central server allocates global transaction information to a transaction corresponding to a transaction initiation request in response to the transaction initiation request of a first transaction server; the global transaction information is distributed to a second transaction server participating in the transaction through the first transaction server, so that the second transaction server feeds back to-be-operated item information corresponding to the transaction according to the global transaction information; item information to be operated corresponding to the global transaction information is stored to a storage server; and when it is monitored that the execution state of executing the transaction by the first transaction server is successful, the to-be-operated item information corresponding to the global transaction information in the storage server is processed, so that the consistency and concurrency of data in the distributed transaction processing process are realized, and the processing efficiency of the distributed transaction is improved.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a distributed transaction processing method, device, system and electronic equipment. Background technique [0002] With the development of the Internet and the ever-changing needs of users, various application businesses are becoming more and more complex, especially those related to the financial industry, most of which adopt distributed architecture to achieve effective services. In a distributed architecture, the same transaction business may need to be accessed across multiple databases, such as read operations and / or write operations. In order to ensure the consistency of data access across multiple databases, most financial transactions are conducted using distributed transactions. deal with. [0003] In practical applications, distributed transactions have final consistency. For example, if a distributed transaction modifies a certain data from A to B, then, during 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
