Hi everyone, On Flight SQL, a column metadata field is needed in order to better disambiguate between SQL column types, for example: A datasource can have different types for string data, like TEXT, VARCHAR, NVARCHAR, etc. Currently there is no way of telling the proper column type name on query results from Flight SQL
We propose adding a "ARROW:FLIGHT:SQL:TYPE_NAME" entry on field metadata, you can see the implementation on this PR: https://github.com/apache/arrow/pull/12747
