lidavidm opened a new issue, #3996:
URL: https://github.com/apache/arrow-adbc/issues/3996
### What feature or improvement would you like to see?
JDBC and ODBC support this.
The challenge is how we want to model them, especially wrt nested types (but
also enums), and how we want to expose them relative to Arrow (e.g. providing a
mapping from database type to Arrow type, and possibly vice versa?)
