🏛️ We launched the DuckDB Library: a curated collection of papers, podcasts, talks and books about DuckDB.
📚 We already have a collection of almost one hundred entities. The thumbnails show whether a piece is from the DuckDB team (yellow) or from others (purple).

SQL's recursive common table expressions (CTEs) have a questionable
reputation: verbose, awkward to read, inefficient to evaluate, ungrokkable
semantics, ripe with arbitrary syntactic restrictions, and basically stale
for 25 years now (since their advent in SQL:1999). Ugh.

I'm grateful that @jwaudberry gave me the chance to set the CTE record straight on his @DisseminatePod. Hear us talk about what you can with iterative computation in SQL, how efficient variants of recursion in SQL found their way into @duckdb, and how trampolines come into play.

CORRECTION: Mihail is doing his PhD at the Data Systems Lab at TU Nuremberg with Andreas Kipf (@andreaskipf) not TU Munich like I say in the trailer
👀 Sneaky plug for Andreas's High Impact in Databases episode... open.spotify.com/episode/5r2…

The report of our @dagstuhl seminar on "Ensuring the Reliability and Robustness of Database Management Systems" is online! All attendees collaboratively wrote it during the seminar, so don't expect it to be polished, but hopefully it is still insightful! drops.dagstuhl.de/storage/04…

Today at the CIDR conference, Marcin Zukowski, Niels Nes and I received the Test of Time award for our @cwi_da paper on vectorized query execution!
Very thankful for this honor & for creating this award going forward.
We gave a talk: bit.ly/cidr2024-test-of-time (with speaker notes)
