We want to have 1 database on 3 servers. Each one should have 1by1 data. So when we write value to server1 - we want to read this value from server2 and from server3. And if after this - server1 will be shut down - we want to have working server2 and server3. And want to write and read data from server 2 and 3.
Which replication factor we should use?
