> Currently, Flink SQL supports only Java `java.util.Map`. Scala maps are treated as a blackbox with Flink `GenericTypeInfo`/SQL `ANY` data type. Therefore, you can forward these blackboxes and use them within scalar functions but accessing with the `['key']` operator is not supported.
> We should convert these special collections at the beginning, in order to use in a SQL statement.
