             Summary: csv.read_csv progress bar
                 Key: ARROW-9111
                 URL: https://issues.apache.org/jira/browse/ARROW-9111
             Project: Apache Arrow
          Issue Type: Improvement
    Affects Versions: 0.17.1
            Reporter: Jeff Hammerbacher


When reading a very large csv file, it would be nice to see some diagnostic 
output from pyarrow. 
[readr|[https://readr.tidyverse.org/reference/read_delim.html]] has a 
`progress` parameter, for example. [tqdm|[https://github.com/tqdm/tqdm]] is 
often used in the Python community to provide this functionality.
