Dataset Api For Lazy Evaluation And Partitioned Data Access

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

Unique: Lazy evaluation API with automatic partition discovery and predicate pushdown that works across local/cloud filesystems via unified abstraction, rather than eager loading or manual partition management

vs others: More memory-efficient than eager Pandas/Spark for large datasets; more transparent than manual partition filtering; supports cloud storage natively where Parquet readers often require manual setup
