New post on the company blog that does a great job showing just how convoluted using ODBC is and how painless database access can be with ADBC and dbc: columnar.tech/blog/odbc-dr...

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!

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/...
