Evaluate your Database Options
DAS requires a PostgreSQL database for storing query event information. During the installation, you can choose to have DAS install and configure a default, embedded PostgreSQL database for use, or you can configure an external PostgreSQL database. You can do this by checking or unchecking the Create Data Analytics Studio database option.
Although DAS provides an option to use the default, embedded database, the embedded database is intended for non-production use. It is strongly recommended to use an external database for production environments.
