Samples Apache Atlas

Apache Atlas Java Client Automation Example

This repository contains a complete, production-ready Java automation example using the Apache Atlas Client V2 API (compatible with Apache Atlas v2.5.0+).

The goal of this project is to demonstrate how data professionals can programmatically interact with a Data Governance and Metadata Catalog tool, automating entity creation, metadata lineage, and classification tagging.

This lab is an integral part of the official training program provided by Ambiente Livre: 👉 Apache Atlas Training - Ambiente Livre

Features Demonstrated

• Programmatic Initialization: Safe bootstrapping of AtlasClientV2 using Apache Commons Configuration to avoid standard classpath/environment file conflicts.
• Entity Creation (hive_table): Dynamic mapping and registration of a Hive table schema (titanic_java_api) within the metadata graph.
• Graph Referencing: Programmatic link establishment between the newly created table and an existing parent database (hive_db) using unique qualifying attributes.
• Automated Data Governance: Automated attachment of security classifications (DADO_SENSIVEL / Sensitive Data tag) directly to the generated entity GUID.
