The article provides a detailed technical analysis of Apache Atlas, describing its core components, type system, JanusGraph‑based graph storage on HBase, the mapping of various metadata types to vertices and edges, and the three‑phase parsing and validation process that together support scalable Hadoop governance.
This article details the architecture, design decisions, and iterative improvements of the Data Catalog product within Volcano Engine's DataLeap suite, covering metadata management, ingestion pipelines, search optimization, lineage capabilities, storage layer enhancements, and future development directions.
This article presents an in‑depth overview of data lineage at ByteDance, detailing the design of storage, display, abstraction, implementation, and storage layers, optimization techniques for real‑time updates and queries, open export methods, practical use cases across asset, development, governance, and security domains, and future directions.
This article presents an in‑depth overview of DataLeap's data lineage capabilities, covering the challenges, multi‑layer model design, implementation with Apache Atlas and JanusGraph, performance optimizations, diverse use cases across asset, development, governance and security domains, and future trends for lineage technology.
This article details ByteDance's 2021 overhaul of its Data Catalog system, the performance regressions encountered after switching to Apache Atlas, and the step‑by‑step backend optimizations—including JanusGraph tuning, Gremlin query refactoring, parallel processing, and write‑path improvements—that reduced latency from minutes to seconds.
This article provides a step‑by‑step tutorial on using Apache Atlas for data lineage, including SQL execution, custom data maps, tagging, field search, detailed installation procedures, runtime commands, and the configuration of Hive and Sqoop hooks for a complete big‑data governance solution.
This article explains what data lineage is, why it is essential for data governance in large‑scale big‑data platforms, compares Apache Atlas with a custom solution, and details the technical choices, architecture, and performance optimizations behind the self‑built duo‑lineage system.
