Documentation for the Quack ADBC driver: adbc-drivers.org/drivers/qua…
ICYMI: Quack lets @duckdb run as a server that clients query over the network, instead of embedded inside an application. It debuted in DuckDB 1.5.3, and 2.0.0 made it substantially faster and more stable.
Congrats to the @ducklabs_com team on a big release!
Get started by installing dbc, the package manager for ADBC drivers: columnar.tech/dbc
Runnable examples showing how to use DuckDB as an ADBC driver in 10+ languages: github.com/columnar-tech/adb…
Query Snowflake, BigQuery, PostgreSQL, SQL Server, and more, all from DuckDB SQL.
Docs and examples: duckdb.org/community_extensi…
Stay tuned for more DuckDB–ADBC news
databow 0.2.0 is out!
One fast CLI for querying 43+ databases. Built in Rust, powered by ADBC.
Now with Parquet export, an improved interactive shell, and Homebrew installation.

Amateurs. Who needs agents for this? I once deleted my whole macOS home directory with a hand-coded script that incorrectly split a file path that contained a directory named ~

We just shipped our official ADBC driver, in partnership with @columnar_tech.

One command installs a signed binary, and it speaks Apache Arrow natively, so results move from ClickHouse into your app with zero conversion.
Ruby, R, and C get real ClickHouse access for the first time.
📣 Introducing databow: one command-line tool to query them all, built with Rust and ADBC.
Query any SQL source that has an ADBC driver (30+ and counting) right from your terminal with one simple CLI.
To install 👉 uv tool install databow

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👇

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.

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 👇
