S3 Tables integrate the Apache Iceberg standard into S3 object storage, enabling optimized storage and querying of large tabular datasets with continual maintenance to improve query efficiency and control costs. The Intelligent-Tiering storage class automatically adjusts storage costs according to data access patterns without impacting performance.
Availability in AWS GovCloud (US-East and US-West) regions extends these benefits to government and regulated workloads requiring high security. The tables are compatible with multiple AWS and third-party query engines, facilitating scalable analytics on sensitive datasets hosted in GovCloud environments.
