Apache Arrow Columnar Format
Arrow specifies a language-independent, columnar in-memory layout with validity bitmaps and contiguous value buffers, so pandas, Polars, DuckDB, and Spark can share the same buffers with zero-copy interchange instead of serializing between formats. It is the reason the modern Python data stack composes: one memory format, many engines.
This Concept is waiting for its first lesson!
