Problems solved by technology

In traditional database-based distributed transactions, the transaction availability is the product of the availability of the database instances participating in the transaction. As long as one instance fails, the transaction operation will fail.
In addition, traditional distributed transactions require multiple network interactions with multiple database instances to achieve two-phase commit, which increases the response time of requests and degrades performance

Abstract

The present invention relates to the transaction processing technology, and discloses a distributed transaction processing method and system. A message-oriented middleware delivers a message to at least one node participating in the distributed transaction to enable the node to execute the local transaction, if the at least one node is failed to execute the local transaction, before nodes failed in execution execute the local transaction, the message-oriented middleware delivers the message to the node again to enable the node to execute the local transaction again, and therefore final consistency of data is achieved. In addition, stagnation caused by the problem that the network is blocked or the message-oriented middleware is abnormal can be prevented by regularly checking status of the nodes.

Description

technical field [0001] The invention relates to transaction processing technology, in particular to a distributed transaction processing method and system thereof. Background technique [0002] The traditional implementation of distributed transactions has the characteristics of requiring the database to provide distributed transactions. Based on the two-phase commit protocol, when each database instance operates successfully, the transaction is considered successful; if one instance fails, the operations of all instances must be rolled back. [0003] Therefore, the inventors of the present invention have found that implementing distributed transactions through a database will lead to a decrease in availability, scalability and performance. In traditional database-based distributed transactions, the transaction availability is the product of the availability of the database instances participating in the transaction. As long as one instance fails, the transaction operation ...
