IBM::ElastiCache::ReplicationGroup
This resource type represents a replication group, which is a group of cache clusters that synchronize their data. A primary cluster stores the data and one or more read replicas store copies of the data.
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.
