I believe that what would happen is that whichever data center has the later clock will win. Every modification you make gets a time stamp (generally set by your client to the current time, if you are using one). I believe that whatever modification happened with the last time stamp is canonical. What would happen if you make conflicting changes with the exact same time stamp? No idea.

Datacenter #1 add column "abc" with value X Datacenter #2 add column "abc" with value Y. What is the result of that situation? Is there any different if the changes will be made withing the same data center? Thanks! Eldad Yamin
