I want to use Doctrine DBAL Cache Adapter as a fallback cache to my other cache options to store external data. Not to store doctrine db results!

The documentation gives me this:
https://symfony.com/doc/6.4/components/cache/adapters/doctrine_dbal_adapter.html

However I don’t find any information if I have to create the caching table myself. Do I? Or is it created automatically? Do I have to choose a name for the table? Is there a standard? How do I pass in my default db connection?

What I have done so far is I configured it as a part of my already complex caching configuration:

framework:
  cache:
    system: cache.adapter.filesystem
    app: cache.adapter.filesystem
    pools:
      cache.sap:
        adapter: cache.adapter.filesystem
      cache.pers:
        adapter: cache.adapter.filesystem
      cache.db: # <-- this is the new one
        adapter: app.cache.adapter.db_cache

services:
  app.cache.adapter.db_cache:
    parent: 'cache.adapter.doctrine_dbal'
    tags:
      - { name: 'cache.pool', namespace: 'sapData', default_lifetime: '0' }

cache.db being the new db cache I want to use.

I also have set up the saving and fetching of the data in the code.

What I haven’t found is any current example configuration of a setup.

I found examples for the PDO cache like this: Symfony3: How to enable PDO/Doctrine cache adapter, the right way?
But this is symfony3 and other examples are even older.
