Description

Hello,

In production, the

Cache::tags('TAGS')->flush();

It only works after a few days and then stopped working completely.

Cache::tags('TAGS')->get(cache_key(['TAGS' => true, 'PAGE' => 1, 'SORT' => 'newest']));
= Illuminate\Pagination\LengthAwarePaginator {#7281
    +onEachSide: 3,
  }

> Cache::tags('TAGS')->flush();
= true

> Cache::tags('TAGS')->get(cache_key(['TAGS' => true, 'PAGE' => 1, 'SORT' => 'newest']));
= Illuminate\Pagination\LengthAwarePaginator {#8029
    +onEachSide: 3,
  }

> Cache::tags('TAGS')->forget(cache_key(['TAGS' => true, 'PAGE' => 1, 'SORT' => 'newest']));
= true

> Cache::tags('TAGS')->get(cache_key(['TAGS' => true, 'PAGE' => 1, 'SORT' => 'newest']));
= null

I was under the expression that it could be the flush function that isn't working so I tried doing the forget function, as expected, it works just fine, but the flush isn't working.

Same issue, it's very hard to reproduce but causing issues in our production environment.

I recommend using this:
https://github.com/swayok/alternative-laravel-cache
https://laravel.com/docs/10.x/cache#pruning-stale-cache-tags
And a maximum of 1 hour of cache. That did fix the problem.

Had the same problem in production for long time. We removed cache:prune-stale-tags command from Console/Kernel.php and it works Ok for these days.

I wasn't even using that before but still having the same issue.

After I used the library I mentioned and added that command, the bug has stopped.

Don't understand why this issue was closed. Redis cache is totally broken in Laravel 10

They just really don't care that much.
