What is the difference between "strong consistency" and "eventual consistency"?
Correct! Well done.
Incorrect.
The correct answer is A) Strong consistency guarantees that all reads return the most recent write immediately; eventual consistency allows reads to return stale data temporarily, converging over time
A
Correct Answer
Strong consistency guarantees that all reads return the most recent write immediately; eventual consistency allows reads to return stale data temporarily, converging over time
Explanation
Strong consistency requires synchronous coordination (often at a latency cost), while eventually consistent systems prioritize availability/performance and allow temporary divergence between replicas.
