For many uses, you may wish to keep workflows for a long time. Argo can save completed workflows to an SQL database.

In addition the table specified in the configmap above, the following tables are created when enabling archiving:
The database migration will only occur successfully if none of the tables exist. If a partial set of the tables exist, the database migration may fail and the Argo workflow-controller pod may fail to start. If this occurs delete all of the tables and try restarting the deployment.

The database user/role needs to have
USAGE permissions on the
public schema of the database so that the necessary table can be generted during the migration.
