Laravel Performance Development Tutorials, Guides & Insights

Retry transactions that fail due to deadlocks:

   use Illuminate\Support\Facades\DB;

   public function handle()
   {
       retry(5, function () {
           DB::transaction(function () {
               $this->order->update(['status' => 'processing']);
               $this->order->process();
           });
       }, 100); // Retry 5 times with 100ms delay
   }

• Query 1: SELECT * FROM posts
• Query 2: SELECT * FROM users WHERE id IN (?, ?, ?) (one query for all authors)

For models with multiple relationships, use nested eager loading:

• Define API limits: A dynamic configuration for API request limits.
• Load Global Preferences: Preferences like application mode (e.g., maintenance or live).
• Control Features: Toggle features dynamically, such as enabling/disabling a user feedback form.

We will use a service provider to load this data and make it available throughout the application.

   <h1>Theme: {{ $sharedData->theme }}</h1>
   <p>API Rate Limit: {{ $sharedData->apiRateLimit }}</p>
   <p>Max Uploads: {{ $sharedData->maxUploads }}</p>

If the data in the singleton changes frequently, you can refresh it when needed.
