Problems solved by technology

During this process, if there is an error during the transaction, it is necessary to manually write the application program for data backflush, restore the database to the state before the transaction, or manually process the inconsistent recovery, which has a large workload, low work efficiency, and is prone to errors and omissions

Embodiment Construction

[0054] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0055] The names involved in the present invention are explained below:

[0056] Distributed system: usually refers to a system whose components are distributed on networked computers, and the components communicate and coordinate actions by passing messages. A distributed system consists of multiple machines that form a set, which is perceived as a whole to provide external services to users, and cooperates between multiple machines through network messages.

[0057]Transaction: It consists of a set of data change operations. We hope that this set of operations can ...

Abstract

The invention discloses a distributed transaction processing method and device. The method comprises the steps of establishing a unified global transaction ID for multiple transactions in multiple databases; performing association processing on read-write operations in a plurality of database to-be-processed data tables and the global transaction ID; updating the to-be-processed data tables in theplurality of databases to obtain an updating result; and submitting or rolling back a transaction record in the to-be-processed data tables according to the updating result, wherein the plurality ofdatabases are isomorphic databases or heterogeneous databases. According to the method and the device, the consistency of data during transaction rollback across multiple databases is guaranteed, meanwhile, an application program does not need to be manually written for data rollback, the workload is small, the working and development efficiency is high, and mistakes and omissions are not likely to occur.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a distributed transaction processing method and device. Background technique [0002] At present, there is a bottleneck in the application of distributed systems in database transactions. There are database performance problems through XA protocol two-phase commit / three-phase commit, and it is difficult to achieve automatic transaction rollback across multiple databases, resulting in greater consistency in distributed databases. question. [0003] The prior art generally uses flexible transactions, such as TCC (Try Confirm Cancel) or SAGA, to perform transaction rollback, which has solved the above-mentioned consistency problem. Take TCC as an example. TCC is a compensating distributed transaction. It has three steps to realize distributed transactions: Try, which is to try the business to be executed. This process does not execute the business, but completes the consistency c...
