> When writing large Parquet files (above 10 GB or so) from Pandas to Parquet
> via the command
> {{pq.write_table(my_df, 'table.parquet')}}
> The write succeeds, but when the parquet file is loaded, the error message
> {{ArrowIOError: Invalid parquet file. Corrupt footer.}}
> appears. This same error occurs when the parquet file is written chunkwise as
> well. When the parquet files are small, say < 5 GB or so (drawn randomly from
> the same dataset), everything proceeds as normal. I've also tried this with
> Pandas df.to_parquet(), with the same results.
> Update: Looks like any DataFrame with size above ~5GB (on disk) returns the
> same error.
