> `BaseRow` is serialized and deserialized as `BinaryRow` by default, so when the key type of the map state is `BaseRow`, we should construct map keys with `BinaryRow` as type to get value from map state, otherwise, you would  always get Null...
> Try it with following SQL:
> {code:java}
> // (b: Int, c: String)
> SELECT 
>       b, listagg(DISTINCT c, '#')
> FROM MyTable
> GROUP BY b
> {code}
