Columnar

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…

For more details and installation instructions, see the dbc 0.2.0 announcement blog post: columnar.tech/blog/announcin…

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 👇

See the documentation at docs.adbc-drivers.org/drivers/databr…

Fetch query results without ODBC / JDBC bottlenecks. The new ADBC driver for @databricks is now in early release. Install it with dbc. Details in comments.

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 @ApacheArrow. Learn more 👉 columnar.tech/blog/announcin…⚡️

Data and AI are evolving fast, but much of today’s infrastructure still runs on standards from the 90s. @columnar_tech, from the team behind Apache Arrow, is bringing an Arrow-native protocol (ADBC) that moves data 10–100× faster across systems like Snowflake and DuckDB. We're excited to lead Columnar's $4M seed round. Read the full Q&A to learn more: bessemervp.team/47d8gWk

ODBC is getting tired. It 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 @ApacheArrow. Watch my talk from the @CMUDB seminar: youtu.be/TjlmNGNx77E

Today's Future Data Systems Seminar Speaker: Ian Cook (@ianmcook) will present @columnar_tech's work on @ApacheArrow 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/futured…

In September the @columnar_tech crew are headed to @PyDataParis 2025 and the first ever @ApacheArrow Summit. The organizer @QuantStack is a dedicated supporter of Apache Arrow. We’re delighted to be sponsoring the event.
