Problems solved by technology

[0005] Although X / OPEN DTP can realize distributed transaction processing, it can only solve the problem of realizing distributed transaction processing within multiple data sources after splitting a single data source, and cannot solve the problem when different multiple data sources are split into multiple data sources. Distributed transaction processing problem

Abstract

The invention provides a distributed transaction processing method and system for multi-data sources. A transaction definition module conducts processing based on the standard of an SG-UAP extension module and in accordance with an OSGI framework, the definition of distributed transactions of different data sources is achieved for call and configuration by transaction developers, and thus the unification and configurability of development of distributed transactions are achieved; a transaction coordinator analyzes configuration files of the distributed transactions defined by the transaction definition module so that the unification and coordination of all the distributed transactions in a whole service system can be achieved, and transaction processing tasks of specified data sources are unified and coordinated and then distributed to different transaction managers; the transaction managers send the received distributed transactions to corresponding resource managers respectively; the resource managers conduct corresponding processing on the distributed transactions according to the configuration files of the received distributed transactions.

Description

technical field [0001] The present invention relates to the technical field of data processing, and more specifically, to a multi-data source-oriented distributed transaction processing method and system. Background technique [0002] With the continuous growth of power grid business, the amount of data continues to increase, such as electricity meter data. The power grid is currently connected to hundreds of millions of electricity meters, and each electricity meter collects data at a point of 15 minutes. The surge in data volume has higher and higher requirements for the database. In order to improve the concurrency performance of data access in the database, the current general practice is to split the data source from a single data source to multiple data sources. According to different business characteristics, we adopt two database splitting strategies: sub-database and table and read-write separation. [0003] Sub-database sub-table and read-write separation realize ...
