Hi @jcdauchy-moodys, I haven't needed support for byte arrays in my usage. Is this an issue you'd be interested in working on?

Hi @JamesOwenHall, I don't have the knowledge to code any rust.

I just wanted to mention this limitation as when I tested on my parquet file, it reported this error.

By the way, can you extract the parquet schema with parquet-cat ?

Thanks anyway, it is a fast solution.
