How to set up LARAVEL cache correctly?

Question

Laravel

Please help me set up LARAVEL cache.
I have these settings. The Cache table has been created. Only value is confusing 'connection' => 'null',
'default' => env('CACHE_DRIVER', 'database'),

'database' => [
            'driver' => 'database',
            'table' => 'cache',
            'connection' => 'null',
        ],

Answer 1

'database' => [
            'driver' => 'database',
            'table' => 'cache',
            'connection' => null,
        ]

This is how the connection will be by default.
Can be specified explicitly

'database' => [
            'driver' => 'database',
            'table' => 'cache',
            'connection' => 'mysql',
        ]

'connection' => 'null' invalid entry
