A user that accesses DDS. Currently, the default username is rwuser.
A database parameter group functions as a container for engine configuration values that can be applied to one or more DB instances. If users create a DB instance without specifying a DB parameter group, the default parameter group is used. The default parameter group contains the default values of the engine and database system optimized for the running DB instances. If users want their DB instances to run with their self-defined engine configuration values, they can simply create a new database parameter group, modify certain parameters, and associate the new DB parameter group to a DB instance. Once associated, all DB instances that use this particular DB parameter group get all the parameter updates to that DB parameter group.
DDS is a database service compatible with the MongoDB protocol and is secure, highly available, reliable, scalable, and easy to use. It provides DB instance creation, scaling, redundancy, backup, restoration, monitoring, and alarm reporting functions with just a few clicks on the DDS console.
