You can set it to cache queries that take longer than x seconds to run.

Yes, I know that it is possible to cache, but if it is turned off, than Metabase will take all data on every refresh from original database, and will not store anything in its database?

It will refresh from the original database.
There is some stuff stored in metabase in the metabase_fieldvalues table. This stores the unique values of the columns used for the filter drop downs. Not used for the dashboard query, but if you’re thinking of GDPR, it will store some user data.
