Fuzzy Match vs Transformation Table

Which one would be faster?


500,000 rows of Fuzzy Matching or if you pre-define those same 500,000 rows in a Transformation Table?


Also the flow of Fuzzy Matching is to try the Transformation Table first then handle the rest with Fuzzy Matching right?

There is no need to compare the two, the transformation table helps you map values from your column to new values before performing the fuzzy matching algorithm.

Some examples of how the transformation table can be used:
