The image shows unified query offload for Cloud Links with an elastic pool leader that is also a Cloud Links provider instance.

There are three user queries directed to Autonomous Database consumers. The consumers direct their Cloud Links requests to an elastic pool leader or to an elastic pool member that is also a Cloud Links provider instance.

With ProxySQL query offload enabled, the provider instance takes the user query and offloads it to a refreshable clone of the provider instance. Three refreshable clones are shown, but there could be any number of refreshable clones available for query offloading.
