Data Synchronization Topologies

Updated on 2023-04-26 GMT+08:00

DRS real-time synchronization supports multiple topology types. You can plan the topology types as required. For details, see the following content.

NOTE:

To ensure data consistency, do not modify the synchronization objects in the destination database.

One-to-One Real-Time Synchronization

You can create a one-to-one synchronization task.

One-to-Many Real-Time Synchronization

You need to create multiple synchronization tasks to implement one-to-many real-time synchronization. For example, to synchronize data from instance A to instances B, C, and D, you need to create three synchronization tasks.

Many-to-One Real-Time Synchronization

You need to create multiple synchronization tasks to implement many-to-one real-time synchronization. For example, to synchronize data from instances B, C, and D to instance A, you need to create three synchronization tasks. Multiple tables can be synchronized to one table.

For details about the restrictions and operation suggestions on the many-to-one scenario, see FAQs.
