Distributed affair submitting method and device thereof

Abstract

The invention discloses a distributed affair submitting method which comprises the following steps of: A, diving a distributed affair into a plurality of sub-affairs; B, executing the sub-affairs in a grading way, wherein a step C is executed if one of the sub-affairs is unsuccessfully executed, and a step D is executed if all the sub-affairs are successfully executed; C, backwards rolling all the sub-affairs in the stage and the former stage of the sub-affairs which are unsuccessfully executed; and D, submitting the update required by the distributed affair. By using the method, the distributed affair submitting efficiency can be improved, the affair can be timely ended and backwards rolled, each affair branch can be processed according to a sequence when the affair branches which form into the distributed affair are multiple and the data is shared among each affair branch which forms into the distributed affair, and the distributed affair can be submitted to a cross-database platform under the condition that all heterogeneous database do not need to support an AX (auxiliary amplifier) protocol.

Description

technical field [0001] The invention relates to the technical field of transaction processing, in particular to a distributed transaction submission method and device. Background technique [0002] Transaction (Transaction) is the unit of concurrency control, which is an operation sequence defined by the user. These operations are either done or not done, and are an indivisible unit of work. Distributed transaction processing means that a transaction may involve multiple database operations. The key to distributed transaction processing is that there must be a way to know all the actions performed by the transaction anywhere, and the decision to commit or roll back the transaction must produce a unified result. (commit all or rollback all). [0003] In the network chat system, the number of users is huge (hundreds of millions of users), and user information needs to be stored in different databases, and the data distribution is carried out according to users and services a...

AI Technical Summary

Problems solved by technology

[0014] 1. Each transaction branch cannot be processed in sequence;

[0015] 2. When there are many transaction branches that make up a distributed transaction, the efficiency of distributed transaction processing is very low, and it is impossible to end the transaction and roll back in time;

[0016] 3. The transaction branches that make up the distributed transaction cannot share data;

[0017] 4. Heterogeneous databases must all support the XA protocol;

[0018] 5. It does not support updating the database and updating the service and client at the same time
