[jira] [Updated] (ARROW-14663) [R] Expose number of threads in
read_csv_arrow() and write_csv_arrow()
[ https://issues.apache.org/jira/browse/ARROW-14663?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Dragoș Moldovan-Grünfeld updated ARROW-14663:
---------------------------------------------
Description: 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. Some functionality (not yet the CSV read or write) allows the user to use the global CPU thread pool, but {{num_threads}} would offer more granular control. (was: 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. )
