This looks fantastic! I’ve been waiting for something like this.

My only gripe is that data loaders don’t seem to support Parquet files, which is really annoying.

There’s an interesting possibility here where you can have large datasets in Parquet, exposed via HTTP, whilst being generated at build time with all the benefits that gives you (being able to read only specific columns, filtering via row group statistics etc). Not dissimilar to the “SQLite over http” WASM demo I guess.

Because right now I need to take my large, nicely compressed dataset and export it as either a CSV or a zip file? And then the browser needs the entire thing, even if I’m just viewing a subset of the data? Which is much bigger and much slower than it needs to be.
