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.

With this launch, customers performing fraud detection, real-time account lookup, or website personalization can define advanced matching rules and get results in real-time without maintaining separate matching infrastructure or re-architecting applications. To enable advanced real-time matching, customers set the enableRealTimeMatching parameter to true on their matching workflow, then call the existing GenerateMatchId API—no new endpoints or migration required.

Advanced real-time matching is available in all AWS Regions where AWS Entity Resolution is available. 

To get started, see Using GenerateMatchId in the AWS Entity Resolution User Guide.
