3.9.9. Persistent Token Store
By default, OAuth tokens are stored in memory only. If you want to persist them in the database as well, you should set the cuba.rest.storeTokensInDb application property to
true. The property value is stored in the database, so you can change its value in the Administration > Application Properties screen.
Expired tokens in the database store must be periodically deleted. The cron expression for scheduled removing of expired tokens is specified in the cuba.rest.deleteExpiredTokensCron application property.
