Fascinating exhibition. One of the public labs I worked in had a large tea room for all lab staff - that doubled as the anatomical pathology library of specimens. TPCH Brisbane, take a bow ...weirdos.

Running a DuckDB as a server, setting up from scratch on an AWS EC2 instance, quickly installing a TPCH benchmark & pulling 1 mio rows over the network: client Amsterdam (client) from the US in 2 seconds
Also, attach DuckDB through Quack as a data catalog. Great demo by @hannes.muehleisen.org.

Sometimes I am depressed about what other engines with full time engineers backed by companies can do. Looking at the list of PRs in Apache DataFusion I feel better. In the works: `tree` explain plans, TPCH dbgen, Spark functions, better out of core sorting, more pushdowns...

Excited about upcoming Parquet improvements in DuckDB. TPCH (sf=10) ~60M rows writing to Parquet V2 went from 4.2s->1.3s (on M4 Max), 1.74Gb->1.43Gb. This greatly benefits ETL, even for one-off experiments from upstream data.

I can't believe i'm saying this, but this election results proves that James Carville is right, and Dems can win on a message of #EconomicRage. Trump won this district by 24 points last election. People are PISSED. Go with that if you want to fix it. www.youtube.com/watch?v=TpCh...

The TPC-H series taking a look at what each query is about is pretty good: www.database-doctor.com/tags/tpch
Today, we are going to talk about estimating filter selectivity and how to fail at it. Two queries are similar enough that we will analyse them together: Q12 and Q14.
