Abstract

The present application relates to a distributed transaction exception processing method, device, computer equipment and storage medium, the method comprising: acquiring the transaction identifier to be submitted; writing the transaction identifier and the transaction identifier into a preset storage space The corresponding status mark to be submitted; send the first submission request for the transaction to the participant node in the distributed system; when the participant node executes the first submission request abnormality, then from the preset storage space Read the to-be-committed status mark corresponding to the identification of the transaction; according to the to-be-committed status mark, send a second submission request to the participant node; the second submission request is used to instruct the participant Nodes commit the transaction. The solution of the present application can save costs.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a distributed transaction exception processing method, device, computer equipment and storage medium. Background technique [0002] With the rapid development of science and technology, various technologies emerge in an endless stream, and distributed transaction processing technology is also widely used in daily applications. Two-phase commit is a commonly used distributed transaction commit method. However, when committing a distributed transaction through two phases, if an exception occurs in the commit phase, the transaction state will be lost, and the final commit of the transaction cannot be completed. [0003] In the traditional method, in the two-phase commit process, if an exception occurs when a participant node submits a transaction, the participant node reads its own transaction log, judges its own state, and then actively communicates with the transaction manager ...
