Upgrade of a set of services dedicated to databases
What’s new ?
We have made updates to the services Distributed Database Middleware (DDM), Data Replication Service (DRS), Document Database Service (DDS) and Relational Database Service (RDS) to expand the scope and cover more operations related to database management in the cloud.
Distributed Database Middleware (DDM)
- Supports the display of historical operations about shards configurations, including retrying, rollback, and service switchover.
- Supports the function of restarting a single node. This function is usually used to restart an abnormal node of a DDM instance.
- Adds the function to modify the virtual IP address of a DDM instance (including its read-only groups) that has load balancing is enabled.
- Supports backup policy configuration for DDM instances. You can manually enable the backup policy of a DDM instance. You can set the retention period, time window, and backup cycle, and back up your DDM instances based on a specified backup policy.
- Overall optimised customer experience in using APIs.
- Optimised error messages.

Data Replication Service (DRS)
- 2 new scenarios: real-time cloud migration from MongoDB to Document Database Service (DDS), and Real-time migration from DDS to MongoDB.
- Supports more versions: migration of MongoDB 3.2.x, 3.4.x and 4.0.x, migration of DDS 3.4.x and 4.0.x, real-time synchronization of MySQL 5.5, 5.6, 5.7, and 8.0, real-time synchronization of Oracle 10g, 11g, 12c, 18c and 19c.
