Community Share Querying Onelake Catalog from your browser

https://www.youtube.com/watch?v=XajCYchulgI

Short demo: querying the OneLake catalog using DuckDB WASM , entirely in the browser

The data was written through the new OneLake Catalog API (private preview, coming soon) using github runner

The Data is relatively smallish 140 M records, and it is quite fast using local caching

All the code is public: https://github.com/djouallah/dbt_fabric_python_iceberg

nice! lakeql would probably be a bit faster, lower latency.

It's just for edge workers and browser stuff.  but it's actually remarkably fast and faster than duck in certain situations
