Abstract

The embodiment of the invention discloses a distributed transaction processing method, a coordination device, a database and electronic equipment. The method comprises the following steps: receiving atimestamp returned after a distributed database executes a pre-submission instruction of a corresponding sub-transaction of a first distributed transaction; after timestamps returned by all distributed databases related to the first distributed transaction are received, sending a timestamp updating instruction to the distributed database related to the first distributed transaction, wherein the timestamp updating instruction is used for indicating to take a returned maximum timestamp as a global timestamp of the distributed database related to the first distributed transaction; and in response to a submission request of the first distributed transaction, sending a sub-transaction submission instruction to a distributed database related to the first distributed transaction, the sub-transaction submission instruction being used for indicating submission of a corresponding sub-transaction of the first distributed transaction and setting a submission timestamp as the maximum timestamp.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a distributed transaction processing method, a coordinating device, a database and electronic equipment. Background technique [0002] A transaction is a sequence of operations consisting of one or more resource management operations. A distributed transaction refers to a transaction in which operations in a sequence of operations involve multiple distributed databases. Read consistency refers to a distributed transaction processing method in which the intermediate state during transaction execution is not easily observed. [0003] The coordination device for distributed transactions often processes distributed transactions according to the X / Open XA protocol (XA protocol for short). However, the XA protocol does not specify how to achieve global read consistency of distributed transactions. Contents of the invention [0004] The embodiment of the present applica...
