February 2025 — NVIDIA/multi-storage-client: Delivered unified path handling, stronger path existence checks, and cache reliability improvements across local and cloud backends. Refactored storage interface to storage_client, and enhanced S3/rclone compatibility. Result: safer, consistent storage operations with lower maintenance costs.

January 2025 monthly summary for NVIDIA/multi-storage-client. Focused on delivering robust multi-storage capabilities, stronger data integrity, and improved startup reliability across providers. Highlights include S3 onboarding improvements, expanded FSSpec functionality, and hardened path and listing logic with targeted robustness fixes.

December 2024 — NVIDIA/multi-storage-client: Delivered two principal updates to improve reliability, flexibility, and performance. Bug fix for performance tests improved type safety by updating the PerformanceMetrics constructor hint to List[Any] and adding a type ignore for ListProxy[Any], and updated the CLI argument for performance tests from 'bucket' to 'prefix' to allow flexible path specification. Feature update to MSC Open Cache Control added a disable_read_cache option in msc.open and refactored large-file handling with safeguards to prevent caching files larger than the configured cache size. These changes enhance data access reliability, reduce cache-related issues, and improve the developer experience for performance testing workflows.
