             Summary: [R] Expose number of threads in read_csv_arrow() and write_csv_arrow()
                 Key: ARROW-14663
                 URL: https://issues.apache.org/jira/browse/ARROW-14663
             Project: Apache Arrow
          Issue Type: Improvement
          Components: R
            Reporter: Dragoș Moldovan-Grünfeld


As of {{readr}} 2.0.0 (and the switch to {{vroom}}) both {{read_csv()}} and {{write_csv()}} allow the user to pass the number of threads to be used when processing (the {{num_threads}} argument). Currently this functionality is not exposed in Arrow. The user can opt to use the global CPU thread pool, but {{num_threads}} would offer more granular control.
