During a two-month period, Smdsbz developed an iterative file listing API for the apache/paimon repository, integrating HadoopFileIO and HadoopCompliantFileIO to support efficient recursive and non-recursive file listing across OSS and S3 backends using Java and Hadoop. The implementation focused on backend scalability, optimizing performance through RemoteIterator and refining code readability by improving string representations for logging. In the milvus-io/milvus repository, Smdsbz addressed a bug in metric type deduction, updating the logic to scan all search results for the first valid metric type, which improved the reliability of metrics in downstream dashboards. The work demonstrated strong backend and API design skills.

Sep 1, 2025September 2025: Milvus core (milvus-io/milvus) — Key feature/bug fix delivered: Metric Type Deduction Robustness. The metric type deduction now scans all search results and returns the metric type from the first non-empty result, replacing the previous assumption that the first result always contained a valid type. This reduces misclassification and improves metric reliability in downstream dashboards. Commit 0c9b1597f275cc87eb577c6c83a83058b102033b with PR #44222 documenting the change.
