AWS Certified Data Analytics Specialty 2021 – Hands-On - S3 Replication Notes

The video tutorial covers Amazon S3 replication, explaining that only new objects are replicated unless the S3 batch replication feature is used for existing objects. It discusses handling delete operations, including optional replication of delete markers, and highlights that deletions with version IDs are not replicated to prevent malicious deletes. The tutorial also clarifies that replication does not chain across multiple buckets. The session concludes with a brief wrap-up.
