This resource type represents a cache cluster, which is a collection of cache nodes.

The blueprint uses the core properties and extended properties, if any, from this resource type. Review and configure the applicable heat resources that apply to your configuration information.

In the blueprint designer, you can configure the properties that the following table includes. Properties are listed as either core or extended. Each type of property is located in separate sections of the heat resource that you can view in the blueprint designer. You set the core properties in the properties section and set the extended properties in the metadata section of the blueprint.
