Using Amazon ElastiCache to cache database query results will ensure that users always receive the most current data without any need for invalidation mechanisms.
False
True
This statement is false because while Amazon ElastiCache can greatly improve application performance by caching database query results, it does not inherently guarantee that users will receive the most up-to-date data. Cached data may become stale if the underlying data in the database changes and the cache is not properly invalidated. Invalidation mechanisms are necessary to remove outdated items from the cache or to update them with fresh data, thus ensuring that users receive current information. Without these mechanisms, users may receive outdated information until the cache expiration or manual invalidation takes place.
