    Project mention: Building an Application Log Analytics Platform with Amazon S3 Tables: Cost Optimization by Migrating from CloudWatch Logs | dev.to | 2026-05-31

    Our team uses Terraform to manage AWS infrastructure. We rely heavily on the modules provided by hashicorp/terraform-provider-aws, but not all API parameters around S3 Tables are supported yet. For example, pull requests have been opened for the partition settings and Intelligent Tiering settings mentioned earlier, but they have not yet been merged. A pull request I previously submitted for Athena managed query results support took about three months to be merged. If these features are important to you, consider reacting to the relevant pull requests and communicating your interest in Iceberg to the maintainers.
