Multi-master on more than 3 servers? But isn’t that possible today unless I’m doing it wrong?
I have 6 servers daisy-chained with a multi-master configuration, example:
And so on, ensuring that Server 6 is replica of 1 to close the “circuit”, for lack of a better word. A key originating on 1 makes its way to 5, albeit with the biggest latency delay of about 1 second.
This is a high traffic production system getting daily use, too. No problems!
