Caching Strategy

Comprehensive caching strategy for Netasampark.

Cache Types​

Application Cache​

  • Storage: Redis
  • TTL: Varies by data type
  • Invalidation: Manual or TTL-based

Query Cache​

  • Storage: Redis
  • TTL: 1 hour
  • Invalidation: On data update

Page Cache​

  • Storage: Filesystem/Redis
  • TTL: 24 hours
  • Invalidation: On content update

CDN Cache​

  • Storage: CDN edge servers
  • TTL: 1 year (static assets)
  • Invalidation: Version-based

Implementation​

Laravel Cache​

// Cache query results
$users = Cache::remember('users.active', 3600, function () {
    return User::where('status', 'active')->get();
});

// Cache with tags
Cache::tags(['users', 'active'])->put('users.active', $users, 3600);

// Cache forever
Cache::forever('config.settings', $settings);

Redis Configuration​

// config/cache.php
'redis' => [
    'client' => 'phpredis',
    'default' => [
        'host' => env('REDIS_HOST', '127.0.0.1'),
        'password' => env('REDIS_PASSWORD'),
        'port' => env('REDIS_PORT', 6379),
        'database' => 0,
    ],
],

Cache Invalidation​

Manual Invalidation​

// Clear specific cache
Cache::forget('users.active');

// Clear tagged cache
Cache::tags(['users'])->flush();

// Clear all cache
Cache::flush();

Automatic Invalidation​

// Invalidate on model update
class User extends Model
{
    protected static function booted()
    {
        static::updated(function ($user) {
            Cache::forget('users.active');
        });
    }
}

Best Practices​

  1. Cache Key Strategy: Use descriptive, unique keys
  2. TTL Strategy: Set appropriate TTLs
  3. Invalidation: Clear cache on updates
  4. Monitoring: Monitor cache hit rates
  5. Fallback: Handle cache misses gracefully
