AWS Entity Resolution now supports real-time matching with advanced matching workflows, enabling customers to match records in milliseconds using complex rulesets through the GenerateMatchId API. Previously, real-time matching was limited to simple rule-based workflows, while advanced rulesets—which support operators like Exact and ExactManyToMany combined with AND/OR logic—could only be used for batch processing that took minutes to hours. This created a critical gap for customers needing real-time entity resolution with sophisticated matching logic.
