During August 2025, Yiy Chen developed the register_table functionality for the influxdata/iceberg-rust repository, enabling seamless registration of existing tables in the AWS Glue catalog. This work involved converting Iceberg table metadata and integrating with AWS Glue APIs to attempt table creation, while implementing robust error handling for scenarios such as non-existent databases or pre-existing tables. Yiy also added an integration test to verify table registration using a metadata location, ensuring reliability and correctness. By leveraging Rust and deep knowledge of AWS Glue and Iceberg Catalog, Yiy’s contribution improved catalog interoperability and streamlined onboarding of legacy datasets for the project.
