A custom deployment combines the previous deployments. For example, as illustrated in the following figure, a primary cluster replicates to a secondary, and then the secondary replicates to a set of tertiary clusters. Essentially, this implementation is a combination of the “Cascaded” and “One-to-many” deployments.
