jwimberl opened a new issue, #7416: URL: https://github.com/apache/arrow-rs/issues/7416
**Describe the bug** Going back some time (< release 33.0.0) the documentation for CommandGetDbSchemas states the catalog_name field should be nullable: > The returned Arrow schema will be: < catalog_name: utf8, db_schema_name: utf8 not null https://docs.rs/arrow-flight/55.0.0/arrow_flight/sql/struct.CommandGetDbSchemas.html However, using arrow-flight v53.2.0 (the newest version I'm able to test with easily), the returned schema has a non-nullable catalog_name field. **To Reproduce** Given a `CommandGetDbSchemas` object `cmd`, examine ``` dbg!(&cmd.into_builder().schema() ``` Output: ``` [... my file...] &cmd.into_builder().schema() = Schema { fields: [ Field { name: "catalog_name", data_type: Utf8, nullable: false, dict_id: 0, dict_is_ordered: false, metadata: {}, }, Field { name: "db_schema_name", data_type: Utf8, nullable: false, dict_id: 0, dict_is_ordered: false, metadata: {}, }, ], metadata: {}, } ``` **Expected behavior** `nullable` should be `true` in the `catalog_name` field to match the documentation. This is also the downstream expectation, e.g. in `adbc_driver_manager.adbc_get_objects()` when using `adbc_driver_flightsql`. **Additional context** I’m using arrow-flight v53.2.0 -- ideally I’d test this on the newest arrow-flight version, but that would be a time investment for compatibility reasons, and I don’t see mention of CommandDbGetTables in release notes or issues. If there is a good chance that this was fixed in a subsequent release, I can make the effort to update and retest. -- This is an automated message from the Apache Git Service.
