AWS Data Exchange now supports adding data sets to existing products
AWS Data Exchange now enables data providers to publish additional data sets to their existing products. Starting today, data providers who want to structure their data across multiple data sets or who want to enrich their products with additional data can now publish additional data sets to their products using the AWS Data Exchange console or programmatically using the AWS Marketplace Catalog API. Once a data set is added to a product, all new subscriptions will have access to the data set and existing subscribers will receive a CloudWatch Event notifying them of the availability of the new data set.
