What is entity resolution in data processing?

Matching messy records—like duplicate providers—across datasets using blockers, scorers, clustering. Essential for clean analytics, but OSS versions demand heavy lifting.

Dedupe vs GoldenMatch: which is faster on large datasets?

GoldenMatch crushes: 207x faster, 14x less memory on 50K NPPES rows. Scales to 500K without choking; dedupe needs tuning heroics.

Does open-source entity resolution scale for production?

Barely—costs explode in time, memory, decisions. Holistic tools like GoldenMatch hint at the future: config data, not the algo.
