[jira] [Created] (HIVE-26685) Improve Path name escaping / unescaping performance

James Petty created HIVE-26685:
----------------------------------

             Summary: Improve Path name escaping / unescaping performance
                 Key: HIVE-26685
                 URL: https://issues.apache.org/jira/browse/HIVE-26685
             Project: Hive
          Issue Type: Improvement
          Components: Hive
    Affects Versions: All Versions
            Reporter: James Petty


When escaping / unescaping partition path part names, the existing logic incurs significant avoidable overhead by copying each character sequentially into a new StringBuilder even when no escaping/unescaping is necessary as well as using String.format to escape characters inside of the inner loop.
