    'max-db-size'           => 12345678900,
    'auto-propagate'        => true,
    },
  },
}

The only compulsory key per database is enable-cache. If false also subsequent keys for that database will be ignored.

The dbconfig parameter is configured with a lookup_option of a deep merge. So particular settings can be appended or overridden from hiera.

nscd::dbconfig:
  netgroup:
    check-files: false
  services:
    enable-cache: false
