What is mattwood.fyi?

A live, structured feed of riffs and links from Matt Wood, Chief AI & Technology Officer at AWS — readable by people and queryable by agents as a typed knowledge graph.

Is there an API and is it free?

Yes. A public, read-only query API is available with no authentication and no API keys. See https://mattwood.fyi/openapi.json and https://mattwood.fyi/docs.

How should an AI agent use this site?

Fetch https://mattwood.fyi/feed.json for the full structured feed, or query the API for keyword/semantic search and the connection graph. See https://mattwood.fyi/agents/ for when-to-use guidance.

DuckLake: Lakehouse Format Built on SQL

Connections

Related to

Ledge: Runnable Markdown Notes Both projects embed structured functionality (SQL catalog / runnable code) into formats typically used for simpler storage (Parquet files / Markdown notes), blurring the line between data and computation
Parseable: Observability Infrastructure Platform Both DuckLake and Parseable address data infrastructure concerns (lakehouse storage vs. observability), positioning themselves as simpler, open alternatives to heavyweight incumbent platforms

Supports

Regenerative Software: The Phoenix Architecture DuckLake's ACID transactions, snapshots, and time travel capabilities directly enable regenerative/phoenix-style architectures by making data state recoverable and auditable without complex infrastructure
Durable Actors DuckLake's snapshot and time-travel semantics provide a storage-layer complement to durable actor patterns — both approaches emphasize stateful persistence and recoverability as first-class concerns
The Slow Formation of Durable Software DuckLake's design philosophy of avoiding vendor lock-in and complex infrastructure aligns with the principles of durable software — choosing simple, stable foundations that outlast trend-driven complexity

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

Supported by

Animations for System Builders: Metastability and Lost Writes DuckLake's lakehouse format built on SQL faces the same distributed consistency challenges (lost writes, concurrent updates) that the animations visualize, making the educational content directly applicable to understanding DuckLake's design tradeoffs

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.
