Ransbury describes how Square leveraged metadata services to improve data discoverability and governance by extending Lyft’s OSS platform, Amundsen. Square represents their data; including databases, clusters, schemas, tables, and columns and privacy-specific features like PII semantic type, data storage security data subject type, and flag, as nodes in a graph database. In addition, Square implemented logic to detect storage locations that may hold sensitive data. In the future, Square plans to apply more granular access controls and facilitate data access based on the metadata centralized in Amundsen.
