Compare DataFrames

Open CarloMariaProietti opened this issue 2 months ago • 0 comments

FIXES #658 It makes possible to compare DataFrame by exploiting Myers difference algotithm whose cost is O((M+N)*D) . M is length of dfA, N is length of dfB, D is length of shortest edit script to get B from A.

Returns a DataFrame< ComparisonDescription >, ComparisonDescription is a schema created specifically for this use case.

It comes with a proper test case.
