Jacob Leverich explains how using open table formats like Iceberg and streaming ETL can eliminate data silos and reduce costs. ## Highlights - Main idea: Lakehouse architectures can replace expensive, siloed observability tools by leveraging cloud-native warehousing and open formats - Practical takeaway: Organizing telemetry data by use case and columnarizing it significantly improves query performance and cost efficiency - Technical breakthrough: Iceberg v3's ability to shred JSON data is a major unlock for handling semi-structured OpenTelemetry data - Failure mode: Relying on generic data pipelines for observability can lead to high latency and unmanageable costs at scale - Strategic advantage: Adopting 'your data in your lake' strategies prevents vendor lock-in and enables unified querying across logs, metrics, and traces ## Topics Lakehouse Architecture, Apache Iceberg, Observability, Streaming ETL, OpenTelemetry, Data Engineering, JSON Shredding, Cloud-Native Warehousing ## Chapters - 6:30 — The Evolution of Data Processing: A look back at the foundations of MapReduce and the shift toward modern data processing architectures. - 12:00 — Challenges in Semi-Structured Data: Discussing the difficulties of parallel processing and relational querying for semi-structured datasets. - 17:30 — The High Cost of Observability Silos: Analyzing how fragmented tools and proprietary formats exacerbate costs and usability issues in observability. - 23:00 — Optimizing for Streaming ETL: The necessity of building specialized streaming pipelines to optimize for end-to-end latency in observability. - 28:40 — Efficient Data Loading in Lakehouses: Strategies for loading data into a lakehouse without creating massive, unmanageable single tables. - 39:30 — The 'Your Data, Your Lake' Strategy: Why enterprises prefer owning their data in open, accessible formats rather than proprietary silos. - 1:07:00 — The Future of Open Table Formats: How advancements like Iceberg v3 JSON shredding are transforming the observability landscape. ## Actions - request_transcript: `POST https://stenobird.com/v1/public/podcasts/data-engineering-podcast/episodes/your-data-your-lake-how-observe-uses-iceberg-and-streaming-etl-for-observability/transcription-requests` — Idempotently request low-priority transcript generation for this episode. - read_markdown: `GET https://stenobird.com/podcast/data-engineering-podcast/your-data-your-lake-how-observe-uses-iceberg-and-streaming-etl-for-observability.md` — Read the agent-friendly Markdown representation of this episode resource.
