Hi,
In our case, we would like to read a big CSV file compressed in .gz format.
We would like to use the `read_csv ` function like this:
`ctx.read_csv('myfile.csv.gz',file_extension=".csv.gz", delimiter=';',
has_header=True, schema_infer_max_records=0, file_compression_type='gzip')`
However, this decompression is not parallel like pigz (54 seconds) compared
to 800 seconds when using the `read_csv` function.
If you could take a look...
