Creating a Parameter Template

Precautions

• DDS does not share parameter template quotas with RDS.
• Each account can create up to 100 DDS parameter templates for the cluster and replica set instances.

Cluster

2. Click in the upper left corner and select a region and a project.
3. Click Service List. Under Database, click Document Database Service to go to the DDS console.
4. In the navigation pane on the left, choose Parameter Templates.

6. Select Cluster for DB Instance Type, specify DB Engine Version, Node Type, New Parameter Template, and Description (optional), and then click OK.
   • Node Type: specifies the node type that this parameter template will apply to. For example, to create a parameter template applying to config, select config.
   • New Parameter Template: The template name can be up to 64 characters. It must start with a letter and can contain only letters (case-sensitive), digits, hyphens (-), periods (.), and underscores (_).
