> Simplification seem to not take into account that the specified field is of array type. In other words，it can simplify "a = 1 AND a = 2" to "false"，but can not simplify “a = ARRAY[1,2] AND a = ARRAY[2,3]” to "false". Obviously, was there no consideration given to the field type being an array？I found this issue while debugging the Flink SQL task.
