By default, Fedora comes configured to write binary resources (i.e. files) to the file system and RDF resources (i.e. objects) to a LevelDB database. It is often desirable to replace the LevelDB database with a different object store. As of 2016-03-04, the configuration for MySQL or PostgreSQL databases are available within the deployable Fedora war file. Below For testing, a file-based objects database may be useful. However, for production installations, it is recommended to use a MySQL or PostgresSQL object store. Below are the steps to use MySQL or PostgreSQL instead of LevelDB.
