最佳缓存时间Laravel的内容

Question

I have a question. What time I need pass in Cache for more posts? I have code on MainController:

$posts = Cache::rememberForever('posts', function() {
    return Post::active()->paginate(15);
});

return view('posts', compact('posts); 

Can I cache on forever?

Note: In my Post model I have global observers: created, deleted, updated, saved. In all these observers I do: Cache::forget('posts'). How will be best? Cache forever or cache posts on time (10 min). Help me please decide. Posts very active adding... Interval: 10, 20, 30 mins

Answer 1

Generally you should cache for as long as possible, to maximize page load speed, but not much longer than you expect new content to show up... Otherwise no one will see the new content.

You could cache for 10 or 30 minutes, because you only add new posts every 10-30 minutes.

If you cache forever, you will not see any new posts after caching. Unless you manually clear the caches.
