ViPR Strong Consistency/Asynchronous Replication
I'm curious to understand how ViPR 2.0 Strong Consistency works in the context of the CAP Theorem, especially because ViPR object replication is asynchronous?

For readers who are not familiar with the CAP Theorem, I have provided the definition below courtesy of Wikipedia:
“In theoretical computer science, the CAP theorem, also known as Brewer's theorem, states that it is impossible for a distributed computer system to simultaneously provide all three of the following guarantees:
1. Consistency - (all nodes see the same data at the same time)
2. Availability - (a guarantee that every request receives a response about whether it was successful or failed)
3. Partition tolerance - (the system continues to operate despite arbitrary message loss or failure of part of the system)”
