How to customize the DoctrineDbalAdapter cache adapter

[pauljura]

Hi, I recently added login throttling to my site and was trying to customize the table name with the DoctrineDbalAdapter to fit with the naming convention of an existing database. I checked here: https://symfony.com/doc/current/components/cache/adapters/doctrine_dbal_adapter.html and here: https://symfony.com/doc/current/cache.html#custom-provider-options

Ultimately I got the answer from here: symfony/symfony#58168

The final complete solution for me was:

# config/packages/cache.yaml
framework:
  cache:
    app: my_adapter
    pools:
        login_throttling.cache:
            adapter: my_adapter

# config/services.yaml
services:
  my_adapter:
    parent: cache.adapter.doctrine_dbal
    arguments:
      $connOrDsn: '@database_connection'
      $options:
        db_table: my_adapter_table

Would be nice to have this documented in the appropriate place. Thanks!
