Pour éviter les biais de data leakage lors des backfills, privilégiez un système de point-in-time correct joins avec des snapshots horodatés. Versionnez vos transformations de features via un registre centralisé (ex: Feast) pour garantir la reproductibilité des expériences et faciliter la collaboration entre équipes.
