> 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 = [1,2] AND a = [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.
