Description
Why
DataComPy is a package to compare two Spark Data Frames. Originally started to be something of a replacement for SAS's PROC COMPARE for Pandas DataFrames with some more functionality than just Pandas.DataFrame.equals(Pandas.DataFrame).
It provides stats and lets users adjust for match accuracy, and specify absolute or relative tolerance for comparison of numeric columns. The package also allows via Fugue to compare Spark DataFrames against other types so: Spark vs Pandas, Spark vs Polars, Spark vs DuckDB etc.
