Rusty was a busy bee across the DuckDB ecosystem today, spinning up work on tomographic-digest while fielding pull requests on the official duckdb/community-extensions repo—proving that even extension authors need code review. Behind closed doors, classified project saw major activity (17 events worth of classified intrigue), with smaller ops ongoing in classified project and classified project. Meanwhile, rustyconover/community-extensions got some love with multiple pushes and branch creations, Query-farm/a5 received attention, and Rusty even starred tobilg/ducklings (a fellow traveler in the data engineering space, it seems). Eighteen commits across five repos is the kind of distributed chaos that keeps a polyrepo developer sharp.

Rusty went full steam ahead across the VGI infrastructure stack, shipping a release on vgi-rpc-python while hammering out 40 commits across vgi-entrypoint, vgi-injector, and related repos. The day saw both repos go public—a significant milestone—plus some aggressive refactoring and cleanup work (DeleteEvents suggest some architectural pruning). Behind closed doors, classified project and classified project kept him busy with classified operations. He also poked around the DuckDB ecosystem, reviewing activity on the official duckdb repo and keeping tabs on duckdb-claude-skills. A day of infrastructure momentum with a release shipped and visibility gained.

Rusty had his hands in multiple pots today, juggling both classified operations and open-source stewardship with impressive dexterity. Behind closed doors, classified project and classified project received attention, while in the public eye, he was busy squashing bugs and reviewing community feedback across the DuckDB ecosystem. He tackled a gnarly issue on adbc_scanner (issue #5) involving float/double corruption and WHERE filter mishaps, then pivoted to provide community support on duckdb-httpfs with thoughtful replies on compression-related issues (#278 and #263). New PRs landed on both duckdb-community-extensions and duckdb-httpfs, while vgi-rpc-python got a fresh release and multiple commits. With 8 commits spread across 6 repos and sustained engagement in the DuckDB community, Rusty proved once again that he's the kind of maintainer who shows up for his users.

VGI Injector: A Tiny HTTPS Download-and-Execute Binary in Zig

I needed a self-contained binary that downloads a program over HTTPS and exec's it — small enough to run in a FROM scratch container with nothing else. Go and Rust couldn't get small enough. Zig could.

Telemetry for DuckDB Extensions Without the Pain

I open-sourced the telemetry client I use across Query.Farm's DuckDB extensions. It's two files, one function call, and it only collects platform and version info.

Releasing vgi-rpc: An RPC Framework Built on Apache Arrow

I built an RPC framework for Python that uses Apache Arrow IPC as the wire format and Python Protocol classes as the interface definition. No .proto files, no codegen — just type annotations.

Acronym-Aware Case Conversions in the DuckDB Inflector Extension

The Inflector extension for DuckDB now supports configurable acronyms, so case conversions preserve terms like HTML, API, and URL as fully uppercase — configured through a native DuckDB setting.

What I've Been Working On

Full activity log →

I've been deep in ecosystem stewardship over the past few months, orchestrating infrastructure upgrades and cross-language contributions while shipping production-ready systems across multiple domains. My focus has centered on future-proofing the DuckDB extension landscape through compatibility crusades and upstream enhancements, while building delightfully practical tools that solve real problems. Behind the scenes, classified operations have kept things interestingly mysterious.

  • Led DuckDB 1.5 compatibility work across 40+ extensions, standardizing documentation and opening PRs across airport, shellfs, webmacro, inflector, and two dozen others while maintaining the entire Query-farm portfolio.
  • Contributed upstream enhancements to Apache Arrow across JavaScript, Swift, Rust, and Go implementations, adding custom metadata support for RecordBatch IPC messages and fixing silent data loss issues in production systems.
  • Shipped a complete vgi-rpc ecosystem with production-ready implementations in Python, C++, Go, and TypeScript, including unified branding, Cloudflare documentation sites, and proper licensing across all four languages.
