Business code synchronization
timing synchronization is not near real
mq near real-time synchronization can be done, Cons: need to add in the business code
data synchronization ultimate solution - Canal
Alibaba's canal is an open source project, pure Java. Based on the incremental database log analysis, provide incremental data subscriptions and consumer services, mainly support some version of Mysql, mariaDB, and the Oracle. Use the middleware can easily detect a change in the data in the database, thus completing the synchronization of data, and can be done with the business code completely decoupled and can achieve real-time synchronization of data, it is the ultimate solution for data synchronization
