File System Abstraction With Multi Backend Support

via “filesystem abstraction layer for multi-backend storage access”

Cross-language columnar memory format for zero-copy data.

Unique: Unified filesystem API that abstracts S3, GCS, ADLS, HDFS, and local files with transparent credential handling and connection pooling, rather than requiring backend-specific code

vs others: More convenient than writing backend-specific code; more transparent than manual credential management; enables Dataset API to work across backends without modification
