Functions and Features

This section describes the main functions and features of DDS.

Migrating Data

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.

Scaling up Storage

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

Changing Instance Class

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

Backup and Restoration

Monitoring Metrics

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.

Managing Logs

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

Configuring Parameters

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

Cross-AZ Disaster Recovery

If the region where your instance is located supports three or more AZs, you can deploy the instance across three AZs to achieve cross-AZ disaster recovery.
