> WASM build doesn't have feature-parity with the "normal" variant

It's a good point, but the wasm docs state that feature-parity isn't there - yet. It could certainly be more detailed, but it seems strange that your company would do all this work without first checking the feature-coverage / specs.

> WebAssembly is basically an additional platform, and there might be platform-specific limitations that make some extensions not able to match their native capabilities or to perform them in a different way.

Note that your docs specifically mentions parquet was supported, but we found out the hard way some specific features turned out not to be supported with WASM + parquet. I did a quick glance at your docs and could not find references to that, so I'm not surprised it was missed.

It was a project that exploited a new opportunity so time-to-market was the most important thing, I'm not suprised these things were missed, and replacing the data loading mechanism was maybe 1 week of work for 1 person, so it wasn't that impactful a change later.

Fair point, thx for sharing your experiences ! You might want to edit the duck-wasm docs in that regard to alert others/the team of this constraint.
