AWS CloudFormation
User Guide (API Version 2010-05-15)


Creates a custom parameter group for DB instances.

This type can be declared in a template and referenced in the DBParameterGroupName parameter of AWS::Neptune::DBInstance.


Applying a ParameterGroup to a DBInstance may require the instance to reboot, resulting in a database outage for the duration of the reboot.


To declare this entity in your AWS CloudFormation template, use the following syntax:


{ "Type" : "AWS::Neptune::DBParameterGroup", "Properties" : { "Description" : String, "Parameters" : DBParameters, "Family" : String, "Tags" : [ Resource Tag, ... ], "Name" : String } }


Type: "AWS::Neptune::DBParameterGroup" Properties: Description: String Parameters: DBParameters Family : String Tags: - Resource Tag Name : String



A friendly description of the DB parameter group. For example, "My Parameter Group".
