Certain tables not showing in data browser

I've had Metabase running a few years now querying our support helpdesk database.
We have built a new helpdesk (same system but newer) and I've added a second database connection to the new DB - MariaDB on Debian 11.

I'm looking at recreating some queries but certain tables are not showing in the data browser but I can query against the missing tables using SQL in Metabase and they are there. It just makes it impossible to use the question builder tool on these tables.

Reading other threads I have forced a manual sync and checked the logs. There are no errors posted there.

Any suggestions?

Looking in the Data Model in the admin section I see there are 3 hidden tables!
So I now have the tables back- but begs the question why were they hidden?


Hi @nodrog
Because for many systems, those table names contains massive amount of computer data, which is not relevant for users in most cases.
For reference: https://github.com/metabase/metabase/blob/master/src/metabase/sync/sync_metadata/tables.clj#L25
