             Summary: Collated strings in complex types supporting operations reverse, array_join, concat, map
                 Key: SPARK-47541
                 URL: https://issues.apache.org/jira/browse/SPARK-47541

          Issue Type: Task
          Components: SQL
    Affects Versions: 4.0.0
            Reporter: Nikola Mandic


Add proper support for complex types containing collated strings in operations reverse, array_join, concat, map (create). Examples:
{code:java}
select reverse('abc' collate utf8_binary_lcase);
select reverse(array('a' collate utf8_binary_lcase, 'b' collate utf8_binary_lcase));
select array_join(array('a' collate utf8_binary_lcase, 'b' collate utf8_binary_lcase), ', ' collate utf8_binary_lcase);
select concat('a' collate utf8_binary_lcase, 'b' collate utf8_binary_lcase);
select map('a' collate utf8_binary_lcase, 1, 'A' collate utf8_binary_lcase, 2);{code}
