📈 50 years of the data stack on one screen. Interactive timeline of access, compute, and storage, 1976 to 2026, from hundreds of sources. How relational systems took over everything, and why the interfaces between layers became the most interesting problem in data. history.columnar.tech

This Friday at PyData Amsterdam 2026, Matt Topol will show how DuckDB (@duckdb.org) and ADBC (@arrow.apache.org) work together to make data analytics in Python faster and easier. Join us on September 11 at 11:05! pretalx.com/pydata-amste... #PyData #Python #DuckDB #ApacheArrow #ADBC #DataAnalytics

Pulling a big result set from Snowflake into Tableau isn't network-bound. It's CPU-bound — burning cycles converting columns to rows and straight back to columns. @ian.columnar.tech of Columnar on ADBC, and the 10-100x you get by deleting that step. link below

This week, the Apache Arrow project released ADBC 24. Highlights include: 📦 Updated client libraries for 9+ languages 🔌 3 updated drivers (14+ more available) 📖 New and improved documentation site See the release announcement for more details: arrow.apache.org/blog/2026/07...

This week we announced a new ADBC driver for Apache DataFusion. DataFusion is Rust-native, but now you can use it from 10+ other languages through the same zero-copy Arrow ADBC interface that connects to 30+ other databases and query engines. Learn more: docs.adbc-drivers.org/drivers/data...

📣 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 More details at columnar.tech/blog/databow-cli

This week we released an ADBC driver for Quack, @duckdb.org’s new native client-server protocol. Now you can query remote DuckDB servers using the same ADBC interface you already use for local DuckDB across 7+ languages—no third-party server extensions required. columnar.tech/blog/quack-a...

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 👇 columnar.tech/blog/dbc-0.3.0

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. Register on Luma: luma.com/3lt47cj9

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.org, which keeps results typed in @arrow.apache.org format end to end: columnar.tech/blog/json-tax

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-dr...

A new startup, @columnar.tech, looks to streamline the copying of tabular data across systems, using @arrow.apache.org and the ADBC API. By @joabj.bsky.social

The future of data connectivity is columnar. Today we launched @columnar.tech to accelerate the shift from slow, row-oriented APIs like ODBC and JDBC to >10x faster alternatives powered by @arrow.apache.org. Learn more 👇

ODBC is getting tired. It just can't keep up with the fast new kids in the data world these days. The next generation is ready to take the torch. Meet ADBC, a fast, modern data connectivity standard built on @arrow.apache.org. Watch my new talk from the @db.cs.cmu.edu seminar: youtu.be/TjlmNGNx77E

Today's Future Data Systems Seminar Speaker: Ian Cook (@ian.columnar.tech) will present @columnar.tech's work on Apache Arrow's database connectivity API (ADBC). ADBC is available in modern DBMSs. Zoom talk open to public at 4:30pm ET. YouTube video available after: db.cs.cmu.edu/events/futur...

In September the @columnar.tech crew are headed to PyData Paris 2025 and the first ever Apache Arrow Summit. The organizer @quantstack.bsky.social is a dedicated supporter of @arrow.apache.org. We’re delighted to be sponsoring the event.
