We are excited to announce that Amazon Personalize now supports incremental bulk dataset imports; a new option for updating your data and improving the quality of your recommendations. Amazon Personalize enables developers to improve customer engagement through personalized product and content recommendations – no ML expertise required. Previously, Amazon Personalize supported two types of data ingestion: full bulk dataset imports for ingesting large datasets, and APIs (PutEvents, PutItems, PutUsers) for real-time ingestion. Now you can keep your existing datasets intact and add new bulk-loaded data without resupplying your entire dataset. Amazon Personalize will automatically update records with the current version if your incremental import duplicates any records found in your existing dataset, further simplifying the data ingestion process.
