Creating a Parameter Template¶
DB parameter templates act as a container for engine configuration values that are applied to one or more DB instances.
Precautions¶
DDS does not share parameter template quotas with RDS.
Each account can create up to 100 DDS parameter templates for the cluster, replica set, and single node instances.
