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

Flattered that the good FP folks put up with me as a DB guy. Thank you for the chat, @kosmikus.bsky.social and @sperbsen.bsky.social. What a fun hour to spend!
We sat down with Torsten Grust who is a professor of DB systems at the University of Tübingen. We talked about the best way to program databases, how to bridge the gap between regular programming languages and databases, and compiling just about everything to SQL. haskell.foundation/podcast/81/
Do you like databases? Do you want to hear two database professors rant about them? Do you need one of those professors to have a Turing Award for databases? If yes, then join Mike Stonebraker and I next Wed Dec 10 @ 1:00pm EST for database hot takes: www.dbos.dev/webcast-2025...

The latest paper from the #1 CMU-DB PhD student @samarchdb.bsky.social is wild compilation magic! He automatically makes UDFs run 300x faster on SQL Server and 1.3x faster on DuckDB. Code: github.com/SamArch27/PR... Paper: www.vldb.org/pvldb/vol18/...
