5.6.0
Starting with this version, loaders will create the database schema you've passed in the config automatically on initialization if it isn't created previously. No further configuration is needed to enable this.
The database user for the loader needs to have permission to create schemas to make this feature work. If the user doesn't have the necessary permission, the loader will just skip this step. In that case, you will need to create the schema manually prior to running the loader.
This feature only affects new deployments. If you are already successfully running the loader, nothing will change.
