We have a phone system with multiple nodes. We want for each node to be able to do a write that will be replicated to the other hosts. Having 10 hosts all in multi master can sticky especially when adding host #11. Is it possible to have three multi master hosts and then have slave nodes that all correct to a central host. For example
We want that if say S1 (slave1) wants to make a write that it gets replicated to M2 and from there back down to S2,S3 as well as M3 and M1. The same would be slave 4 made a write. It would “share” it with M3 which would then send it over to M1 and M2 (causing it to be replicated to slave1, slave2 and slave3) Is that possible?
