Worked on the trinodb/trino repository to optimize Azure FileSystem detection for Hierarchical Namespace (HNS) support, focusing on improving performance for Azure Data Lake Gen2 workloads. Refactored the Java-based AzureFileSystem implementation to replace the previous blob-existence check with a direct query to Get Account Info, reducing unnecessary API calls and enabling faster, more reliable HNS detection. This change streamlined initialization and operational efficiency for cloud storage integrations. Leveraged expertise in Azure, cloud storage, and file systems to deliver maintainable code that enhances the speed and reliability of Azure-backed workloads, demonstrating a thoughtful approach to performance-oriented engineering challenges.
