Functions and Features

With Data Replication Service (DRS), you can migrate self-built MongoDB databases or other cloud MongoDB databases to DDS in real time. DRS simplifies data transmission between databases and reduces data transmission costs.

If the storage you purchased cannot meet your requirements, you can scale up the instance.

If the CPU or memory of an instance cannot meet your service requirements, you can change the instance class on the console.

• DDS supports automated backup and manual backup. The maximum retention period for an automated backup is 732 days. A manual backup can be retained until you delete it.
• DB instances can be restored using backup data. Replica set instances support point-in-time recovery at the instance level, database level and table level.

DDS monitors key performance metrics of instances and DB engines in real time, including the CPU usage, memory usage, storage space usage, command execution frequency, delete statement execution frequency, insert statement execution frequency, and number of active connections.

DDS allows you to query and download database error logs and slow SQL logs.

DDS allows you to manage parameter templates and modify parameter template settings on the console.
