Hi,
Let’s say that I have 2 datacenters, a key is changed on both of my datacenters in the exact same time (even in 1-2 seconds diff).
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!
