Rusty Conover
Data infrastructure engineer and founder of Query.Farm. Building DuckDB extensions, scaling data platforms, and writing about what I learn along the way.
Recent Activity
View all →Rusty spent the day focused on modernizing the WebAssembly build infrastructure and supporting community work across multiple DuckDB-related projects.
A productive day spanning multiple repositories across the DuckDB ecosystem and supporting infrastructure projects.
VGI RPC Libraries — Rusty released v0.6.2 and v0.6.1 across the three VGI RPC language implementations (vgi-rpc-typescript, vgi-rpc-go, and vgi-rpc-python), with multiple commits on main pushing updates to each.
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.
TIME Data Type Compatibility Across Databases
A survey of the TIME data type across 14 databases, comparing supported ranges, maximum values, and whether the special value 24:00:00 is accepted.
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 spent the last few months deeply embedded in ecosystem stewardship, particularly around DuckDB's extension landscape and cross-language infrastructure work. I led a major compatibility push across the Query-farm portfolio while contributing upstream enhancements to Apache Arrow and shipping a complete production-ready vgi-rpc ecosystem. Beyond the public work, I've balanced high-visibility open-source contributions with classified operations that kept things operationally interesting.
- Spearheaded DuckDB 1.5 compatibility across 40+ extensions and standardized documentation structures across 29 repositories, future-proofing the entire Query-farm ecosystem.
- Contributed upstream improvements to Apache Arrow across JavaScript, Swift, Rust, and Go implementations, fixing silent data drops in RecordBatch IPC serialization and dictionary message handling.
- Shipped Fair Weather Friend—a production weather app with PWA support, stargazing mode, cycling-specific scoring, and dog-walking safety alerts alongside the complete vgi-rpc ecosystem with unified branding and documentation infrastructure.
