> SubqueryBroadcastExec retrieves the partition key from the broadcast results based on the type of HashedRelation returned. If the key is packed inside a Long, we extract it through bitwise operations and cast it as Byte/Short/Int if necessary.
> The casting here can cause a potential runtime error. We should fix it.
