Thanks for your contribution. To be honest i didn't get the logic. What i did: 1. Built it from the PR's branch 2. Started standalone Flink 3. Via sqlClient submitted several queries ```sql SELECT array_union(array[1], array[2]); -- result array[1, 2] -- this is OK ``` ```sql SELECT array_union(array[1], array[2, 3]); -- result array[1, 2, 3] --- this is OK ``` ```sql SELECT array_union(array[1], array[2, 3, null]); -- result array[1, 2, 3, 0] --- this is NOT OK ``` ```sql SELECT array_union(array[1], array['this is a string']); -- result [1, 16] -- this is NOT OK ``` ```sql SELECT array_union(array[1], array['this is a string']); -- result [1, 16] -- this is NOT OK ``` ```sql SELECT array_union(array[1], array[array[1, 2, 3]]); -- result [1, 24] -- this is NOT OK ``` -- This is an automated message from the Apache Git Service.
