Ontology-Driven Observability: Building a Knowledge Graph at Netflix Scale

Connections

Related to

Before Pixels: Modular Industrial Dashboards Both deal with industrial-scale monitoring and dashboard systems; Netflix's ontology-driven observability graph and modular industrial dashboards both tackle the problem of representing complex system state relationships visually
DuckLake: Lakehouse Format Built on SQL Both are large-scale data infrastructure solutions built on principled abstractions—DuckLake uses SQL as a foundation for lakehouse format while Netflix uses ontology principles for knowledge graphs, both enabling structured querying of complex operational data
GenRec: LLM-Native Recommendation System at Netflix Both are Netflix-scale engineering solutions—GenRec addresses recommendation systems while the knowledge graph addresses observability—sharing the same infrastructure challenges and ontology-driven data modeling at massive scale
Parseable: Observability Infrastructure Platform Both address observability infrastructure at scale; Parseable is an observability platform while Netflix's knowledge graph provides ontology-driven observability, representing complementary architectural approaches to the same domain

Supports

Semantic ID-based Generative Retrieval for Podcast Discovery at Spotify Netflix's knowledge graph for system relationships supports semantic ID-based retrieval concepts at Spotify—both use structured semantic representations to manage complex entity relationships at production scale

Animations for System Builders: Metastability and Lost Writes Ontology-driven observability at Netflix scale deals with detecting and understanding distributed system failures — the animation approach to teaching metastability complements observability tooling aimed at catching such failures in production

I'm Matt Wood, and this is For Your Information. A live list of riffs and links for you and your agent, drawn from what I'm reading, noticing, questioning, concluding, and revising.
