[jira] [Created] (SPARK-14225) Cap the length of toCommentSafeString at 128 chars

Reynold Xin created SPARK-14225:
-----------------------------------

             Summary: Cap the length of toCommentSafeString at 128 chars
                 Key: SPARK-14225
                 URL: https://issues.apache.org/jira/browse/SPARK-14225
             Project: Spark
          Issue Type: Improvement
          Components: SQL
            Reporter: Reynold Xin
            Assignee: Reynold Xin


I just saw a query with over 1000 fields and the generated expression comment is pages long. At that level printing them no longer gives us much benefit. We should just cap the length at some level.
