When you use DataWorks to synchronize data, you can use only exclusive resource groups for data integration to run real-time data synchronization nodes. This topic describes the resources and configurations required to run real-time data synchronization nodes.

What to do next

After you plan and configure resources, you can configure data sources. You must configure network connectivity for the data sources and permissions to access the data sources. This facilitates the creation of a real-time data synchronization node. You can synchronize data only from PolarDB, Oracle, or MySQL to Hologres. You can select a data source based on your business requirements. For more information about how to configure a data source, see Configure a source PolarDB data source, Configure a source Oracle data source, and Configure a source MySQL data source.
