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 @arrow.apache.org, 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:

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

Apache Arrow is 10 years old 🎉
The first git commit landed on 2016-02-05. Now Arrow has 10+ official implementations and a growing third-party ecosystem.
Read our celebratory blog post for some tidbits of Arrow history, and our outlook on the present and future.

Fetch query results without ODBC / JDBC bottlenecks. The new ADBC driver for Databricks is now available in early release. Install it with dbc.
Data plumbing has never mattered more. From the maturation of open standards like ADBC and Iceberg to the infrastructure needed for agentic workflows, here are our 10 predictions for 2026 🔮

Was anyone else like me, wondering if you can use ADBC with $5 Postgres from @planetscale.com? Well, you can! (No surprise)

ADBC drivers in #Java? Yes. The latest release of ADBC adds a JNI layer that lets Java apps load drivers, run queries, and fetch results fast in @arrow.apache.org format. Read the new blog post from @ian.columnar.tech and David Li for examples and perf comparisons vs. JDBC. Link in comments👇

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

At Row Zero we get amazing speeds ingesting data from Snowflake and other databases that can export column-oriented data. But there's a long tail of data stores that we're forced to slow down for, because they only allow row-oriented export. Here's hoping we can change that!
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...

Thanks @andypavlo.bsky.social for hosting this series!
Register for the Apache Arrow Summit Paris 25 (October 2nd) at: www.meetup.com/pydata-paris...
The event is hosted by @pydataparis.bsky.social
We are looking forward to seeing you there and talking about all things Arrow.
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.
Next Tuesday, get ready to meet the mind behind #Pandas & #ApacheArrow!
@wesmckinney.com shares his origin story (Part 1) on #TheTestSet. From speedruns to shaping the data stack, this is one you won't want to miss.

2025 is shaping up to be a breakout year for fast query result transfer with Apache Arrow. But what exactly makes it so fast? David Li, Matt Topol, and I break it down in this new blog post: arrow.apache.org/blog/2025/01...
[🎥 Watch] Apache Arrow is a columnar format and multi-language toolbox for fast data interchange and in-memory analytics.
Matt Topol, Arrow PMC member, talks about Arrow subprojects and how you can get involved with the project. https://buff.ly/40qNPAL

Would love to see more discussion of this. To Andy's point we have this wonderful Arrow eco system that's underdeveloped. In a world of columnar data we're still stuck using ODBC/JDBC for connectivity to most data systems. Hard to get some vendors to even talk about ADBC.

You might like to try Ibis: ibis-project.org. It was created by Wes McKinney (also the author of pandas) as a solution to some problems pandas couldn't solve well. It's had a lot of recent growth and improvement. There's a tutorial for users coming from dplyr: ibis-project.org/tutorials/ib...
