One interesting feature of DuckDB is that it can run queries against HTTP ranges of a static file hosted via HTTPS, and there's an official WebAssembly build of it that can do that same trick.

So you can dump e.g. all of Hacker News in a single multi-GB Parquet file somewhere and build a client-side JavaScript application that can run queries against that without having to fetch the whole thing.

You can run searches on https://lil.law.harvard.edu/data-gov-archive/ and watch the network panel to see DuckDB in action.

In that case, then using duckdb might be even more performant than using what we’re doing here.

It would be an interesting experiment to add the duckdb hackend
