Currently the defaults in ``/node/src/main/resources/reference.conf`` are as shown in the first example. This is currently
the only configuration that has been tested, although in the future full support for other storage layers will be validated.

To add additional data source properties (for a specific JDBC driver settings) use ``dataSource.`` prefix with property name (e.g. `dataSource.customProperty = value`).
