Laravel's implementation of cache doesn't allow failures - if your Redis dies, your app dies too.
New fail_safe driver aims to solve this by catching and logging all exceptions and instead
returning null/false as if the value was simply not found in cache:
// config/cache.php
[
'fail_safe' => [
'delegate' => [
'driver' => 'redis',
'connection' => 'cache',
'lock_connection' => 'default',
]
]
]
// code
Cache::forever('key', 'value');
// redis died here
Cache::get('key'); // returns null and logs the exception
