Abstract

The invention involves a distributed data synchronization method and system.The method includes steps: the scheduler needs to perform synchronous tasks to the source database, and adjust the interval time according to the elasticity of the query results; the scheduler selects one of the synchronous components in the synchronous component cluster to perform the task;Use multiple parallel thread processing; synchronous components read the synchronous dataset from the source database and perform data processing; synchronous components generate temporary unique logo to replace the original unique logo of synchronous dataset, and then write the quantity of the synchronous data set to the target databaseThere are updated old data records in the target database, and finally restore the original unique logo of the synchronous data set in batches.The present invention has greatly improved the performance of the entire data synchronization.

Description

technical field

[0001] The present invention relates to data synchronization technology, in particular to a distributed data synchronization method and system. Background technique

[0002] Data synchronization is a means of maintaining data consistency among multiple data sources and is widely used in various computer systems. There are several common application scenarios for data synchronization: 1. Computer system realizes disaster recovery backup through data synchronization to avoid single point of failure; 2. Computer system realizes system load balancing through data synchronization and improves system performance; 3. Multiple systems Data sharing is achieved by means of data synchronization. There are generally two ways to realize data synchronization. One is to read the BinLog file of the database, obtain the modification operation statement in it, and send it to the database to be synchronized for execution to realize data synchronization. The second method is t...
