Before you configure a data synchronization node to synchronize data from a data source to the Hologres data source, you must add both data sources to DataWorks for subsequent source and destination configurations.

Prerequisites

Before you add data sources, make sure that the following operations are performed:
  • Prepare data sources: A source data source and a destination data source are created.
  • Create and grant permission to an account: An account that is used to access data sources is created.

Precautions

DataWorks provides workspaces in basic mode and standard mode. A workspace in basic mode does not isolate the development environment from the production environment. A workspace in standard mode isolates the development environment from the production environment.

If you use a workspace in standard mode, you must separately add data sources to the development environment and production environment.

Add a source PolarDB for MySQL data source

To add a source PolarDB for MySQL data source, you must configure information such as the network connection type and the access account and password as planned. For more information about how to add a source PolarDB for MySQL data source, see Add a PolarDB data source.

If the source PolarDB for MySQL data source that you want to add fails the connectivity test, follow the instructions described in What do I do if the PolarDB data source cannot be connected? to handle the exception.

Add a source Oracle data source

To add a source Oracle data source, you must configure information such as the network connection type and the access account and password as planned. For more information about how to add a source Oracle data source, see Add an Oracle data source.

Add a source MySQL data source

To add a source MySQL data source, you must configure information such as the network connection type and the access account and password as planned. For more information about how to add a source MySQL data source, see Add a MySQL data source.

Add a destination Hologres data source

For more information about how to add a destination Hologres data source, see Add a Hologres data source.

What to do next

After you add data sources, you can create and run a data sync node to synchronize data from the source data source to the destination data source.

For more information, see Configure and manage a real-time synchronization node.
