[Feature request] "Verify" command

[Florian R. Hölzlwimmer]

Hi, would it be possible to add a "verify" command to check for corrupt parquet files?

[SteveLauC]

This is kinda easy to implement? With a corrupted parquet file, trying to read it would result in:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: General("Invalid Parquet file. Corrupt footer")', src/main.rs:11:55
