[GitHub] [arrow] pstalcup opened a new issue, #37356: IPC Deserialization does not support LargeUtf8 type
pstalcup opened a new issue, #37356:
URL: https://github.com/apache/arrow/issues/37356
### Describe the enhancement requested
Feather files generated by polars can only output LargeUtf8 instead of Utf8, so any dataframe I write from polars with a string in it will fail to deserialize in JS.
### Component(s)
JavaScript

You can look at the referenced PR and see for yourself.
You could also go a parquet route via https://github.com/kylebarron/parquet-wasm/ + https://github.com/kylebarron/arrow-js-ffi, which will downcast the large string to string automatically when it crosses the wasm boundary. These aren't tested as well as the official Arrow IPC reader though
