Detailed explanation-1: -Strict Consistency Model : “The strict consistency model is the strongest form of memory coherence, having the most stringent consistency requirements.
Detailed explanation-2: -Linearizability is one of the strongest notions of consistency, uh, which says that each operation by a client is visible or is available instantaneously, and when I say instantaneously I mean in real time to all the other clients.
Detailed explanation-3: -Strong consistency: The data in all nodes is the same at any time. At the same time, you should get the value of key1 in node A and the value of key1 in node B. Weak consistency: There is no guarantee that all nodes have the same data at any time, and there are many different implementations.
