[jira] [Created] (SPARK-40194) SPLIT function on empty regex should truncate trailing empty string.

Vitalii Li created SPARK-40194:
----------------------------------

             Summary: SPLIT function on empty regex should truncate trailing empty string.
                 Key: SPARK-40194
                 URL: https://issues.apache.org/jira/browse/SPARK-40194
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.4.0
            Reporter: Vitalii Li


E.g. `select split('hello', '')` should convert to `['h', 'e', 'l', 'l', 'o']` instead of `['h', 'e', 'l', 'l', 'o', '']`. Requires explicit `limit` parameter to preserve trailing empty string.
