Real-Time Synchronization
Real-time synchronization refers to the real-time flow of key service data from sources to destinations while consistency of data can be ensured. It is different from migration. Migration means moving your overall database from one platform to another. Synchronization refers to the continuous flow of data between different services.

Only whitelisted users can use this function. To use this function, submit a service ticket. In the upper right corner of the management console, choose Service Tickets > Create Service Ticket.
Supported Database Types
DRS supports real-time synchronization between databases of various types, and many-to-one synchronization.

Synchronization Methods
DRS supports three synchronization modes: full synchronization, incremental synchronization, and full+incremental synchronization.
Full synchronization: All objects and data in non-system databases are synchronized to the destination database at a time. This mode is applicable to scenarios where service interruption is acceptable.
Incremental synchronization: Through log parsing, DRS replicates incremental data to keep sources and destinations in sync.
Full+Incremental synchronization: DRS allows you to synchronize data in real time. After a full synchronization initializes the destination database, an incremental synchronization parses logs to ensure data consistency between the source and destination databases.
