Consistency is almost used by the industry, so that when we are discussing consistency, we are actually unable to determine whether the consistency the other party said is consistent with our own.
Consistency: Consistency, Consensus: Synergy, these two concepts are very easy to confuse.
What we often say about consistency (Consistency) in a distributed system refers to multiple copies of the same data, its external performance data consistency, such as linear consistency, causal consistency, eventual consistency, etc., are all used To describe the consistency in the copy problem. Consensus is different. In simple terms, the consensus problem is a process in which multiple nodes reach the same state through a certain algorithm. In my opinion, consistency emphasizes results and consensus emphasizes process.
