It is supported to use Oracle as the application database? if it is so, which versions?
The metabase shows Postgres, MySQL or MariaDB dsatabase as "Highly Recommended" but don't say if they are the only ones supported.
- Using Metabase with an H2 application database is not recommended for production deployments. For production deployments, we highly recommend using Postgres, MySQL, or MariaDB instead. If you decide to continue to use H2, please be sure to back up the database file regularly.
