### Is your feature request related to a problem or challenge? Based on the discussion in https://github.com/apache/datafusion/issues/11268#issuecomment-2211125762, we will support the MAP literal to create a map value. Referring to the [DuckDB syntax](https://duckdb.org/docs/sql/data_types/map.html), we can use syntax like: ```sql SELECT MAP {'key1': 10, 'key2': 20, 'key3': 30}; ``` ### Describe the solution you'd like After #11361, we now have two functions: `map` and `make_map`. We can use `UserDefinedSQLPlanner` to implement the proposed syntax and rewrite it to the `map` function. As @jayzhan211 mentioned in https://github.com/apache/datafusion/pull/11361#issuecomment-2221710127, we can also use `ExprPlanner` to handle the `make_map` function. Since `make_map` is less efficient than the `map` function, we should retain only the faster `map` scalar function implementation. For more details, see the previous discussions and benchmark results in #11361. ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
