| # Overview |
| |
| Atlas is a scalable and extensible set of core foundational governance services – enabling |
| enterprises to effectively and efficiently meet their compliance requirements within Hadoop and |
| allows integration with the whole enterprise data ecosystem. |
| |
| Apache Atlas provides open metadata management and governance capabilities for organizations |
| to build a catalog of their data assets, classify and govern these assets and provide collaboration |
| capabilities around these data assets for data scientists, analysts and the data governance team. |
| |
| |
| ## Features |
| |
| ### Metadata types & instances |
| * Pre-defined types for various Hadoop and non-Hadoop metadata |
| * Ability to define new types for the metadata to be managed |
| * Types can have primitive attributes, complex attributes, object references; can inherit from other types |
| * Instances of types, called entities, capture metadata object details and their relationships |
| * REST APIs to work with types and instances allow easier integration |
| |
| ### Classification |
| * Ability to dynamically create classifications - like PII, EXPIRES_ON, DATA_QUALITY, SENSITIVE |
| * Classifications can include attributes - like expiry_date attribute in EXPIRES_ON classification |
| * Entities can be associated with multiple classifications, enabling easier discovery and security enforcement |
| * Propagation of classifications via lineage - automatically ensures that classifications follow the data as it goes through various processing |
| |
| ### Lineage |
| * Intuitive UI to view lineage of data as it moves through various processes |
| * REST APIs to access and update lineage |
| |
| ### Search/Discovery |
| * Intuitive UI to search entities by type, classification, attribute value or free-text |
| * Rich REST APIs to search by complex criteria |
| * SQL like query language to search entities - Domain Specific Language (DSL) |
| |
| ### Security & Data Masking |
| * Fine-grained security for metadata access, enabling controls on access to entity instances and operations like add/update/remove classifications |
| * Integration with Apache Ranger enables authorization/data-masking on data access based on classifications associated with entities in Apache Atlas. For example: |
| * who can access data classified as PII, SENSITIVE |
| * customer-service users can only see last 4 digits of columns classified as NATIONAL_ID |
