Most of the configuration options above can be also provided as environment variables prepending the name with `DATAPUSHER_`, eg `DATAPUSHER_SQLALCHEMY_DATABASE_URI`, `DATAPUSHER_PORT`, etc.


By default DataPusher uses SQLite as the database backend for the jobs information. This is fine for local development and sites with low activity, but for sites that need more performance should use Postgres as the backend for the jobs database (eg `SQLALCHEMY_DATABASE_URI=postgresql://datapusher_jobs:YOURPASSWORD@localhost/datapusher_jobs`. See also [High Availability Setup](#high-availability-setup). If SQLite is used, is probably a good idea to store the database in a location other than `/tmp`. This will prevent the database being dropped, causing out of sync errors in the CKAN side. A good place to store it is the CKAN storage folder (if DataPusher is installed in the same server), generally in `/var/lib/ckan/`.
