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, @columnar.tech & @clickhouse.com announced the official ADBC driver for ClickHouse. It enables zero-conversion, end-to-end @arrow.apache.org transfer for analytics & AI applications. It works across C/C++, Go, Java, JavaScript/TypeScript, Python, R, Ruby, Rust, & more. Link in comments👇

This week, we released a new ADBC driver for Apache Spark, built in collaboration with dbt Labs. It’s available now as a pre-release, and we’d love feedback from early adopters. Try it out 👉 dbc install --pre spark Docs and quickstarts are linked in the comments

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

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

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: columnar.tech/blog/adbc-dr...
