How does the Empty all services data action work?¶
In order to preserve global performance, this action won’t remove all
data from the database right after you launched it. Entries will be

could block all your database for several hours.
Anyway, it doesn’t mean the data will stay into your database indefinitely. It will be removed in the future, depending on you data retention policy.
