> Input data in JSON data file has prevailing and trailing spaces for some of the values.
Trimming the whitespace and then doing an order by over the trimmed results, we see the query
returned results in in correct ordering. Each value is a string value. Some of the strings
are very long in length (they have 1000-2049 characters in them).
