Document Database Service (DDS), compatible with MongoDB, is a secure, high availability (HA) database service that is reliable, scalable, and easy to use. It provides functions such as one-click deployment, elastic capacity expansion, disaster recovery, backup, restoration, monitoring, and alarm reporting.
