             Summary: Calcite engine. Support DISTINCT ON expression
                 Key: IGNITE-14539
                 URL: https://issues.apache.org/jira/browse/IGNITE-14539
             Project: Ignite
          Issue Type: Improvement
          Components: sql
            Reporter: Taras Ledkov


Now DISTINCT ON expression isn't supported.
e.g.:
{{SELECT DISTINCT ON (lastName) firstName, lastName FROM Person WHERE ... }}
Test: {{aggregate/distinct/test_distinct_on.test_ignored}}
