"Amundsen Data Discovery: Searchable Metadata for Analytics Teams" Analytics organizations don't struggle because they lack data-they struggle because they can't reliably find, understand, and trust it fast enough to make decisions. This book is written for experienced analytics engineers, data platform engineers, and senior analysts who are tired of institutional memory and ad-hoc Slack support as the primary "catalog." It reframes discovery as an end-to-end systems problem and shows how Amundsen turns metadata into a durable interface for analytics work. You'll learn how to design a metadata contract that survives migrations, schema churn, and multi-environment realities; how Amundsen's microservices (Frontend, Search, Metadata) interact; and why the metadata graph and Elasticsearch index each matter for different questions. The book dives deep into modeling invariants, idempotent update semantics, relevance tuning, and responsible use of popularity signals. A substantial implementation focus covers Databuilder ingestion pipelines, multi-source enrichment from warehouses and BI tools, and verification loops that pinpoint failures across extraction, publishing, indexing, and UI. Expect production-grade guidance: Docker Compose for fast iteration, Kubernetes topology and scaling, and operational discipline for Neo4j and Elasticsearch as stateful dependencies. Prerequisites include comfort with distributed systems basics, data warehousing concepts, and running services in containers; in return, you'll leave with a playbook for building a trusted discovery platform and an
