Question

A developer is building a data-processing pipeline. A producer application writes a new object to an Amazon S3 bucket and, immediately afterward, a consumer process performs a GET request for that exact object key it just created. The developer is concerned about whether the consumer will reliably read the newly written object without adding retry logic. Which statement accurately describes the consistency behavior the developer can rely on?

Accepted Answer

S3 provides strong read-after-write consistency for new object PUTs, so a subsequent GET of that key returns the latest data without retries.

Answer

S3 offers only eventual consistency for new objects, so the GET may return a 404 and the developer must implement exponential backoff retries.

Answer

Strong consistency is only available if the developer enables S3 Object Lock on the bucket, otherwise reads are eventually consistent.

Answer

Strong consistency requires versioning to be enabled on the bucket; without versioning the GET may return stale data.
