Vortex files implement the Arrow Dataset interface permitting efficient use of a Vortex file within query engines like DuckDB and Polars. In particular, Vortex will read data proportional to the number of rows passing a filter condition and the number of columns in a selection. For most Vortex encodings, this property holds true even when the filter condition specifies a single row.
