yas3fs

Leverages Amazon SNS for real-time cache invalidation across multiple nodes, enabling efficient shared access to S3 data in clusters, as detailed in the README's architecture.

Uses multi-part uploads and downloads to maximize throughput for large files, with configurable settings for part size and parallelism.

Buffering allows file access during downloads, enabling streaming use cases like media playback directly from S3 without full file retrieval.

Provides signed URLs via xattr for secure, time-limited access to files, simplifying integration with applications that need temporary S3 object access.
