D.1. About Consistency
Consistency is the policy that states whether it is possible for a data record on one node to vary from the same data record on another node.
For example, due to network speeds, it is possible that a write operation performed on the master node has not yet been performed on another node in the store, a strong consistency guarantee will ensure that data which is not yet fully replicated is not returned to the application.
