Data lineage tracking at scale: How this offline platform processes petabytes every day

In modern data environments, the ability to track data lineage at scale is essential to ensure traceability, compliance, and quality. This article describes how an offline platform designed to process petabytes daily addresses the challenges of orchestration, observability, and lineage querying using technologies such as DolphinScheduler, YAML, Neo4j, and proprietary tools developed in Go.

High-level architecture: The platform clearly separates ingestion, processing, storage, and visualization. Data flows are orchestrated with DolphinScheduler to coordinate batch tasks and temporal dependencies. Pipeline definitions are versioned in YAML, allowing execution replay and change auditing. Neo4j is used as a graph database to model relationships between tables, files, pipelines, and transformations. Internal tools developed in Go handle massive metadata extraction, normalization, and efficient writing to Neo4j.

Ingestion and normalization: To handle petabytes daily, the platform prioritizes offline batch processes that group changes and apply them incrementally. Extractors written in Go connect to data lakes, databases, and messaging systems to capture metadata and transformation lineage. YAML schemas describe each pipeline, its inputs, outputs, and parameters, facilitating automatic generation of documentation and data integrity tests.

Lineage modeling with Neo4j: Neo4j allows representing entities such as datasets, tables, columns, jobs, and users as nodes, and transformation relationships as edges. This graphical representation facilitates complex queries about upstream and downstream impact, for example, identifying all dashboards affected by a change in a column. Optimized queries and indexing in Neo4j enable interactive responses even with hundreds of millions of relationships.

Orchestration with DolphinScheduler: DolphinScheduler handles scheduling the execution of dependent tasks and transformation chains. Its integration with extractors and Go jobs allows coordinating processing windows, running validations, and triggering lineage exports to Neo4j. Task-based scheduling facilitates retries, parallelization, and controlled re-execution of pipeline segments, reducing risk in processes that handle large volumes.

Custom tools in Go: The utilities developed in Go were designed for performance and low resource consumption. They include connectors to extract metadata, ETL catalog scraping, log adapters, and YAML definition parsers. These tools also perform deduplication, aggregation, and enrichment of metadata before persisting it in the Neo4j graph, ensuring consistency and scalability in environments with high change rates.

Strategies for scaling offline processing: To scale to petabytes daily, the platform applies several layered techniques: data partitioning by time window and source, batch processing with size limits, compression and efficient serialization of metadata, intermediate caches to reduce repeated queries, and incremental pipelines that only process deltas. Additionally, a retention and historical summarization policy is implemented to keep queries fast without sacrificing audit capability.

Observability and governance: Traceability is complemented with metrics and alerts that monitor latency, failure rates, and discrepancies in counts between stages. Automatic reports detect anomalies in lineage and trigger validation workflows. Governance uses rules based on graph metadata to apply permissions and restrictions, integrating security and audit controls that are critical in regulated environments.

Typical use cases: Analyzing the impact of schema changes, identifying obsolete data sources, auditing transformations for compliance, and rebuilding historical pipelines for reproducibility. These capabilities allow data teams to accelerate deployments, mitigate risks, and improve data quality at massive volume.

Advantages of this offline approach: Reduced operational cost through batch processing, better compression of operations, robustness against ingestion spikes, and the ability to perform complex historical analyses without affecting OLTP processes. The combination of DolphinScheduler, YAML, Neo4j, and Go tools offers reproducible traceability and a solid foundation for advanced analytics.
