[jira] [Created] (ARROW-10399) [R] Fix performance regression from cpp11::r_string

Neal Richardson created ARROW-10399:
---------------------------------------

             Summary: [R] Fix performance regression from cpp11::r_string
                 Key: ARROW-10399
                 URL: https://issues.apache.org/jira/browse/ARROW-10399
             Project: Apache Arrow
          Issue Type: Bug
          Components: R
    Affects Versions: 2.0.0
            Reporter: Neal Richardson
            Assignee: Neal Richardson
             Fix For: 3.0.0


On a taxi CSV read demo, reading a data.frame went from ~7 seconds to ~30 seconds. One of the cpp11 changes was identified to be a cause, and reverting it recovered the lost performance.
