Absolutely fantastic piece of software. Even beyond being used as engine for analysis, it's amazingly versatile for ingesting and reshaping data. Great job.

We've found DuckDB 2.0 to be way faster on high core count machines on EC2. Not just reading data from S3, but the actual computations too. Much more likely to see 100% utilisation up to about 128vCPUs or 192vCPUs, and that CPU usage to translate into workloads completing faster.

Still don't usually see a speedup past about 192vCPU, but prior to 2.0, speed would top out at more like 64vCPU, so this is a big win.

That has enabled us to scale Splink (FOSS record linakge software) to 1bn records in 10 mins, which as far as I'm aware makes it the fastest linkage engine of this kind. Most of this performance comes from simply delegating the big calculations to the DuckDB engine! https://moj-analytical-services.github.io/splink/topic_guide...

Thanks to the team for all their work!

The fact that can now be used as a client-server architecture is a game changer. It will for sure replace many data stacks that now run on many servers with tons of cpu and ram
