S3 Tables and Iceberg version

Currently, Amazon S3 Tables supports Apache Iceberg, but the exact version supported is not explicitly stated in the provided information. The latest confirmed version of Iceberg supported by AWS services is 1.7.1, which is used in AWS Glue version 5.0.

S3 Tables is designed to work with the Apache Iceberg standard and provides built-in Iceberg support, optimized for analytics workloads. It offers features like continual table optimization, improved query performance, and higher transaction rates compared to unmanaged Iceberg tables.

However, there is no specific mention of support for Apache Iceberg 1.9.0 or its geospatial data types feature in the context of S3 Tables. Given that S3 Tables is a relatively new feature (introduced in late 2024) and is rapidly evolving with new capabilities, it's possible that support for newer Iceberg versions could be added in the future.

For the most up-to-date information on supported Iceberg versions and features in S3 Tables, it would be best to check the latest AWS documentation or contact AWS support directly.
