Amazon S3 Tables now offer more cost-effective compaction operations for Apache Iceberg tables, with processing fees reduced by up to 90%. S3 Tables provide storage that is optimized for analytics workloads, which automates maintenance operations like compaction to continuously improve query performance and reduce storage costs. With these compaction price reductions, the per-object price is now 50% lower, while per-byte processing prices are 90% lower for binpack compaction and 80% lower for sort and z-order compaction.
S3 Tables provide three automated compaction strategies, designed for varying query patterns. The default binpack strategy combines files for basic optimization. Sort compaction organizes data by specific columns to reduce file scans during queries. Z-order compaction helps when querying multiple columns at once. S3 Tables automatically apply hierarchical sorting during compaction when a sort order is defined in table metadata, with z-order compaction available through the S3 Tables maintenance API.
These reduced S3 Tables compaction prices took effect July 1, 2025 in all AWS Regions where S3 Tables is available and will be automatically reflected in your AWS bill. To learn more, visit the Amazon S3 pricing page and S3 Tables maintenance documentation.
