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. @ianmcook of Columnar on ADBC, and the 10-100x you get by deleting that step. link below

We just shipped our official ADBC driver, in partnership with @columnar_tech. clickhou.se/4gx3nwq 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.

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
