Amazon S3 Tables now support all data types in the Apache Iceberg V3 specification, AWS announced. New capabilities include deletion vectors, row lineage, and native types for semi-structured data (variant), geospatial data (geometry, geography), nanosecond timestamps, and unknown columns. AWS says deletion vectors replace V2 positional delete files with a compact binary format, reducing compaction overhead. Row lineage fields enable incremental pipeline processing without full table scans. Teams can create new V3 tables or upgrade existing V2 tables in place; downgrades are not supported. New V3 data types require Apache Spark 4.0 or later, such as AWS Glue 6.0 or Amazon EMR 8.1. The feature is available now across all supported AWS regions at no additional charge.
