Abstract

The invention provides a distributed transaction processing method, device and system. The method comprises the following steps of: receiving a branch request of a target transaction sent by a reception terminal, wherein the branch request comprises information of a modification item of the target transaction; judging whether the modification item is occupied or not; and if the judging result is negative, forming a mapping relationship between a first global transaction log and the modification item, wherein the first global transaction log is a global transaction log of the target transaction. According to the method, device and system, the operation of establishing a shadow table in a database corresponding to a resource manager can be avoided and the expenditure of the shadow table is maintained.

Description

technical field

[0001] The present invention relates to Internet technology, in particular to a distributed transaction processing method, device and system. Background technique

[0002] The so-called transaction is an operation unit in the database. In this operation unit, all operations either succeed or fail, and the execution result is irreversible. Transactions have four basic characteristics: atomicity, consistency, isolation, and persistence , also referred to as ACID characteristics of transactions. With the development of the Internet and the changing needs of users, the application of distributed transaction systems is becoming more and more extensive.
