This week we released version 0.3.0 of dbc, the package manager for modern database drivers. This release makes dbc: 🧩 Easier to embed inside apps 🤖 Easier to run with AI agents ⚙️ Easier to set up in CI workflows Read the announcement and install or upgrade 👇

AI coding tools speed up how we build data-driven apps. But legacy database access patterns slow us down. Join us for a live hands-on workshop to learn how ADBC makes database access faster, more portable, and better suited to analytical and agentic work. Sign up at link below👇

JavaScript and TypeScript developers have been paying “the JSON tax” on every database query: parsing, coercing, and validating results. Our latest post introduces the ADBC driver manager for @nodejs which keeps results typed in @ApacheArrow format end to end. Link in comments👇

Repo with runnable GnuCOBOL demos for SQLite, DuckDB, and Snowflake: github.com/columnar-tech/…

We heard you: ADBC is great, but you need it on mainframes. Introducing ADBC for COBOL. The same connectors that work with Python, Rust, and Go now work with a language originally designed for punch cards. Blog post and repo in the comments.

The fastest operation is the one you don’t have to do. When a database natively supports @ApacheArrow, ADBC can speed up fetching and ingestion by eliminating costly row/column conversions. How much faster is it in practice? We ran some benchmarks to find out. Link below 👇

This week we shipped 4 updated ADBC drivers with major performance gains: ⏱️ 3× faster queries (BigQuery, MSSQL) ⚡ >30× faster ingest (MySQL, Trino) How we achieved it, what’s next, and what vendors can do to unlock even more speed: columnar.tech/blog/adbc-driv…

This week we shipped the second release of dbc, the command-line tool for installing and managing ADBC drivers: 📦 More drivers (Oracle & Teradata) 🔐 Private registries 🛠️ Easier to embed in other tools 🧑‍💻 Better human UX 🤖 Better agent experience Full details in comments 👇
