Comparison

class versus.Comparison

Shared interface for backend-specific comparison objects.

versus.compare() returns concrete subclasses of this type. DuckDB comparisons expose DuckDB relations; Spark comparisons expose Spark DataFrames. The helper method names stay the same across backends.

Comparison.value_diffs	Return rows where one column differs between the inputs.
Comparison.value_diffs_stacked	Return a stacked view of value differences for multiple columns.
Comparison.weave_diffs_wide	Return a wide view of differing rows with split columns.
Comparison.weave_diffs_long	Return a long view of differing rows stacked by input.
Comparison.slice_diffs	Return rows from one input that differ in the selected columns.
Comparison.slice_unmatched	Return rows from one input whose keys are missing in the other.
Comparison.slice_unmatched_both	Return unmatched rows from both inputs.
Comparison.summary	Summarize which difference categories are present.
Comparison.close	Release backend-specific cached state for the comparison.
