Hello,

Imagine this setup:

When clustering graphite you have, for example, server1 with carbon cache and aggregation and server2 with the same setup. There is also a carbon-relay that sends all metrics to both carbon instances. 

My question is what happens when a metric doesn't make it to one carbon instance but does to another. The whisper databases are not in sync then, server1 says metric x = a and server2 says metric x = b. 

What does graphite do when you want to graph this data point?

Is there a way to ensure that your replicas are consistent?
