Redis – Laravel cache key prefix is prepended with database prefix

The cache prefix setting has the default value:

'prefix' => env('CACHE_PREFIX', Str::slug(env('APP_NAME', 'laravel'), '_').'_cache')

But when I cache some data (using Redis), the cache key has an unexpected format:

app_database_app_cache:some-data

The cache key is prefixed with the database prefix. I expected the cache key to just be:

app_cache:some-data

Is this the correct behavior, and is it possible to change it somewhere?

    I somehow didn't notice the REDIS_PREFIX env var which prepends a prefix. The file caching of config.php also made it harder to debug.

    For those who still lost, Redis key is the combination of two variables in Laravel.

    1. REDIS_PREFIX – config/database.php
    'prefix' => env('REDIS_PREFIX', Str::slug(env('APP_NAME', 'laravel'), '_').'_database_'),
    1. CACHE_PREFIX – config/cache.php
    'prefix' => env('CACHE_PREFIX', Str::slug(env('APP_NAME', 'laravel'), '_').'_cache'),

    If you see an unexpected prefix or suffix in your key, you’d better look at those two.
