A pipeline needs recent event replay for consumers and seven years of queryable historical retention at an appropriate cost. Which design principles should it apply? Select 2 answers.

1. Assume any stream automatically retains all data forever without a retention setting.
2. Persist history to an appropriate durable store such as S3, with cataloging, query layout, and lifecycle policies for the long-term requirements.
3. Use the stream retention window for operational replay and recovery of recent consumer progress.
4. Delete stream records before any durable sink commits them and rely on downstream consumers to reconstruct the missing events.
5. Keep only consumer checkpoints and discard the event payloads needed for future historical queries.
