                 Key: PARQUET-1750
                 URL: https://issues.apache.org/jira/browse/PARQUET-1750
             Project: Parquet
          Issue Type: Improvement
            Reporter: David Mollitor
            Assignee: David Mollitor


{{RowRanges}} maintains an internal {{ArrayList}} with a default capacity (10). 
 However, sometimes it is known ahead of time that only a single instance of 
{{Range}} will be added.  For these cases, do not instantiate an {{ArrayList}}
