October 2025: Delivered a configurable AWS KMS endpoint feature for Apache Iceberg, enabling kms.endpoint to direct KMS requests to custom endpoints. Updated core AWS integrations (AwsClientFactories and AwsProperties) to honor the new setting and added tests to verify behavior. This work improves interoperability with KMS-compatible services and supports private-cloud deployments, enhancing security posture and deployment flexibility across environments.

Month: 2025-02 Key contributions and outcomes: 1) Key features delivered - Implemented Configurable AWS signer headers via properties for apache/iceberg-python. This feature adds mechanism to include base headers defined in properties into the AWS signer headers, enabling custom headers to be specified in properties to configure signing and improve integration with AWS services. Commit: d47970b5843893d3f46f70602cb104785eb605a6 (#1610). 2) Major bugs fixed - No major bugs fixed in February 2025 for apache/iceberg-python. 3) Overall impact and accomplishments - This feature improves AWS signer customization and integration, reducing onboarding friction for AWS users and enabling more flexible signing configurations, contributing to higher interoperability and reliability of iceberg-python when used with AWS services. 4) Technologies/skills demonstrated - Python development, property-driven configuration, AWS signer integration, code signing considerations, and contribution to an open-source project (Git, collaboration, and review practices).
