Data Visibility in AWS DataZone Domains

AWS DataZone is a sophisticated platform for managing data across various environments including AWS, on-premises, and third-party data sources. It is structured around domains, which act as separate entities for organizing and controlling data assets, users, and their associated projects. To facilitate data sharing and visibility across different domains within a single AWS account, such as in your case with df-test-1 and df-test-2, DataZone offers functionalities for publishing data to its catalog and enabling access through subscription workflows. This involves users discovering available data assets, requesting access, and the asset owners granting the necessary permissions. Moreover, the platform supports integrations with AWS Glue and Amazon Redshift, among others, allowing for the automated publishing of data assets to the DataZone catalog during scheduled data source runs​​​​.

In terms of accessibility and interaction, Amazon DataZone is designed for both manual and programmatic use. Data assets can be managed and accessed through its web-based portal or via APIs, AWS CloudFormation, and other AWS tools. This flexibility is crucial for domain administrators, data users, and system developers who are involved in data analytics and governance. To address your specific issue of not seeing data from one domain in another, it's essential to ensure that the data assets are correctly published in the DataZone catalog and that subscription requests are created and approved as per the platform’s guidelines. This process ensures that once a subscription is approved, the necessary access is granted, allowing users in a domain to query and utilize data from another domain​​​​.
