(DataX is Alibaba's open source offline synchronization tool for heterogeneous data sources. Data synchronization function. In order to solve the synchronization problem of heterogeneous data sources, DataX has changed the complex mesh synchronization link into a star data link, and DataX is responsible for connecting various data sources as an intermediate transmission carrier. When you need to access a new data source, you only need to connect this data source to DataX to realize seamless data synchronization with the existing data source.)
