• AWS News Blog Announcing replication support and Intelligent-Tiering for Amazon S3 Tables | Today, we’re announcing two new capabilities for Amazon S3 Tables: support for the new Intelligent-Tiering storage class that automatically optimizes costs based on access patterns, and replication support to automatically maintain consistent Apache Iceberg table replicas across AWS Regions and accounts without manual sync. • Organizations working with tabular data face two common challenges. • First, they need to manually manage storage costs as their datasets grow and access patterns change over time. • Second, when maintaining replicas of Iceberg tables across Regions or accounts, they must build and maintain complex architectures to track updates, manage object replication, and handle metadata transformations. • S3 Tables Intelligent-Tiering storage class With the S3 Tables Intelligent-Tiering storage class, data is automatically tiered to the most cost-effective access tier based on access patterns. • Data is stored in three low-latency tiers: Frequent Access, Infrequent Access (40% lower cost than Frequent Access), and Archive Instant Access (68% lower cost compared to Infrequent Access).
Article Summaries:
- AWS has announced two new features for Amazon S3 Tables. First, the Intelligent‑Tiering storage class automatically moves table data between Frequent, Infrequent, and Archive Instant Access tiers based on usage, reducing costs without affecting application performance. Second, S3 Tables now support replication, allowing read‑only replicas of Apache Iceberg tables to be created across AWS regions and accounts. Replication preserves snapshot relationships and updates replicas within minutes, enabling global datasets, lower query latency, compliance, and data protection. Both capabilities can be managed via the AWS CLI and default bucket settings.
