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

CORRECTION: Mihail is doing his PhD at the Data Systems Lab at TU Nuremberg with Andreas Kipf (@andreaskipf.bsky.social‬) not TU Munich like I say in the trailer

Here's what we've got in store for you!

🧨 E2: Abigail Kim (@abigalekim.bsky.social) (Carnegie Mellon University) - Anarchy in the Database (deep dive into DBMS Extensibility)

Sounds great! We are always on the look out for new guests -- we should make this happen.
