AWS Certified Developer Associate DVA-C02 Practice Question
You are developing an application that uses Amazon DynamoDB to store user activity data. The nature of the application requires that when a user performs an action, the most recent data must be shown immediately in their activity feed. Which type of read operation should you use to ensure the most up-to-date data is always retrieved?
To ensure the most up-to-date data is retrieved, a strongly consistent read should be used. Strongly consistent reads return a response with the most recent data, reflecting all writes that received a successful response before the read. Eventual consistency might return stale data since it allows for the possibility of reads occurring before all of the recent write operations have fully propagated to all copies of the data. Write-through and read-through are caching strategies, not consistency models and thus do not directly pertain to the consistency of database read operations.
