What type of read does a strongly consistent read provide compared to an eventually consistent read?

A strongly consistent read guarantees that when you read data, you receive the most recent write for that item. This means that after a successful write operation is confirmed, any subsequent read operation will reflect that update immediately. Because of this consistency, the system may need to coordinate across multiple internal components to ensure that the latest data is delivered, which can result in higher latency.

In contrast, an eventually consistent read might not reflect the most recent updates immediately. The system prioritizes availability and partition tolerance, leading to faster responses but at the cost of potentially delivering stale data. This can result in lower latency, as the system does not always have to ensure synchronization across all nodes when serving read requests.

Therefore, the property of strong consistency inherently comes with trade-offs such as higher latency due to the need for coordination and assurance of the most current data being returned to the user.
