Data Lineage Agent: Architecture, Integrations, & Security

Modern enterprise data architectures require high security, multi-system connectivity, and automated agent cooperation. The Data Lineage Agent is designed to operate seamlessly within a collaborative multi-agent ecosystem, integrate directly with cloud data warehouses and orchestration tools, and run within a strict zero-data-storage security sandbox.

Multi-Agent Architecture & Cooperation

In the Datapunkt ecosystem, specialized agents work together under the Root Orchestrator to design, validate, execute, and monitor data pipelines. The Data Lineage Agent functions as the primary observer, capturing metadata from each agent to compile an end-to-end lineage map.

The Agent Cooperation Pipeline

1. Source Catalog Agent: Accesses physical data sources (e.g., PostgreSQL, MySQL), profiles datasets, and publishes schema definitions.
2. Data Modeling Agent: Ingests source structures and constructs target schemas (such as Raw Vault or analytical models) optimized for the warehouse.
3. Mapping Contract Agent: Compares source schemas with target schemas to define specific transformation rules and data quality constraints in a version-controlled YAML contract.
4. Transformation Agent: Reads the generated mapping contracts and executes physical transformations (using SQL or Python scripts).
5. Data Quality Agent: Analyzes data streams to validate validation rules and track operational data quality.
6. Data Lineage Agent (This Agent): Gathers metadata from all the above agents to compile a comprehensive, column-level graph of the entire data pipeline.

By combining these specialized agents, the platform automates the entire lineage lifecycle without requiring developers to manually document dependencies.

Platform & Tool Integrations

The Data Lineage Agent supports a wide array of databases, files, orchestration platforms, and collaboration tools.

Supported Data Sources & Destinations

• Cloud Warehouses: Snowflake, Google BigQuery, Amazon Redshift, and Databricks.
• Relational Databases: PostgreSQL, MySQL, and Microsoft SQL Server.
• Storage Systems: Amazon S3, Google Cloud Storage (GCS), and Azure Data Lake Storage (ADLS).

Orchestration & Metadata Engines

• dbt (data build tool): Parses manifest.json and catalog.json files to instantly render your dbt lineage graph.
• Apache Airflow / Prefect / Dagster: Integrates via OpenLineage listener extensions to capture job execution states, inputs, and outputs.
• Apache Atlas / Collibra / Alation: Supports direct export of metadata packages to populate enterprise catalogs.

Collaboration & Chat Integrations

• Teams & Slack: Connect the agent to Microsoft Teams or Slack to query lineage paths directly from shared channels. Contact support on the Datapunkt site to request setup tokens.

Security, Privacy, and Data Protection

We understand that data lineage involves looking at sensitive schema definitions, database structures, and internal business logic. The Data Lineage Agent is designed with strict security-first principles to keep your assets safe.

Zero-Data Storage Policy

A core security benefit of the Datapunkt architecture is that we do not store your operational database records:

• The agent only scans metadata, such as table names, column structures, and configuration code.
• The agent never accesses, queries, or stores the actual data rows, client records, or transaction logs.
• Your business data remains within your private network boundaries.

Transient In-Memory Processing

To prevent unauthorized metadata access, all lineage construction, schema parsing, and dependency mapping are executed transiently in memory:

• Lineage graphs are generated in real-time during your active session.
• Once the session is closed, the in-memory cache is immediately cleared.
• No technical metadata or mapping graphs are saved on our platform databases.

Encryption & Secure Access

• Transit Encryption: All communications between your databases, orchestrators, and the agent are protected using TLS 1.3 encryption.
• Credential Isolation: The agent connects to metadata stores using read-only credentials with minimal access scopes, ensuring it cannot modify schemas or read data rows.

Multi-Region Residency Controls

You can specify the region where the agent instance and session metadata reside to comply with corporate and local regulations:

• United States (US)
• Europe (EU)
• Asia-Pacific (APAC)
• Customer-Specified Location (for custom deployments)

Troubleshooting & Support

Follow these practices to resolve common operational challenges:

Disconnected Lineage Nodes

If parts of your pipeline appear as disconnected nodes in the graph, ensure that you have loaded the corresponding Mapping Contract or dbt execution files. Without these documents, the agent cannot determine how the upstream tables connect to downstream views.

Missing OpenLineage Events

If the agent is not receiving real-time pipeline events, verify that the OpenLineage listener is properly configured in your orchestration engine (such as Airflow or Spark) and that the correct endpoint URL and API keys are specified.

Benefits: What Makes It Good?

• Zero-Storage Security Architecture: Only processes schema metadata, ensuring that your sensitive transactional data never leaves your environment.
• Automatic Multi-Agent Sync: Integrates with the entire Datapunkt agent suite, updating your lineage paths immediately whenever upstream schemas or transformations change.
• Seamless Tool Integrations: Plugs directly into your existing dbt and Airflow workflows, harvesting lineage details without requiring code rewrites.
• Multi-Standard Compliance: Exports audit-ready documents conforming to W3C PROV and OpenLineage, ensuring compliance with strict global standards.
