Super proud to share a new QLever milestone. We loaded one trillion triples on a single AMD Ryzen 9 machine with 16 cores and 128 GB RAM 🚀. Index size is 6.5 TB and the dataset runs even with less memory.

Dataset: qlever.dev/one-trillion/

I had to check if this was for real, but he actually posted it and even defends it, saying anyone who disagrees just doesn’t get it.

QLever codebase is ~ 130k lines of C++, after 10 years (minus tests). Just to give you an idea of how stupid this statement is.

First minimal PoC DSL on the left by my Zazuko colleague Michael. Middle is generated YAML.

🚍🏙️ Spatial analytics in QLever is crazy good! Here’s a query from the OpenStreetMap dataset showing all Jakarta buildings within 400m of a public transport stop. You can play with the examples on their endpoint:
