I would like to establish a Protocol A with Proxy between node-b and node-c. This will be over a WAN. Then I want to establish a Protocol C between node-a and node-b. node-a will know nothing about the proxy or node-c. When I create the resource on node-b that syncs with node-a I will simply use the resource already established to sync with node-c. My goal is to make node-a operate as efficient as possible without the connection to node-c slowing it down. That is an interesting scenario for sure, but it seems you have designed a split brain scenario, and that's bad. The hole I see is what if node b is primary on Cluster A, but secondary on Cluster B, you are now pushing BAD data onto the Primary in Cluster A, and have just trashed all your data. I may be misinterpreting your use of the term Proxy, but I don't see how to maintain consistency. Regards, Nik Nik Martin VP of Business Development nfina Technologies, Inc.
