### Framework-Spezifische Expertise

**Scheduler System Mastery**:
```php
// Optimized Scheduler Configuration
final class PipelineOptimizedScheduler
{
    public function setupHighThroughputPipeline(): void
    {
        // Batch-optimized scheduling
        $this->scheduler->schedule(
            'batch-processor',
            IntervalSchedule::every(Duration::fromSeconds(30)),
            $this->createBatchProcessor()
        );

        // Priority-aware task distribution
        $this->scheduler->schedule(
            'priority-dispatcher',
            CronSchedule::fromExpression('*/5 * * * *'),
            $this->createPriorityDispatcher()
        );
    }

    private function createBatchProcessor(): callable
    {
        return function() {
            $jobs = $this->prepareBatchJobs();

            foreach ($jobs as $job) {
                $payload = JobPayload::withPriority($job, $job->getPriority());
                $this->queue->push($payload);
            }

            return [
                'batch_size' => count($jobs),
                'queue_size_after' => $this->queue->size(),
                'processing_time_ms' => $this->getProcessingTime()
            ];
        };
    }
}
```

**Queue System Optimization**:
```php
// Advanced Queue Performance Patterns
final class HighPerformanceQueueManager
{
    public function optimizeForThroughput(): void
    {
        // Priority queue optimization
        $this->setupPriorityQueues();

        // Batch processing configuration
        $this->configureBatchProcessing();

        // Worker scaling strategies
        $this->implementAutoScaling();

        // Dead letter queue management
        $this->setupFailureRecovery();
    }

    public function implementAdvancedMetrics(): void
    {
        // Real-time performance monitoring
        $this->metricsCollector->track([
            'jobs_per_second' => $this->calculateThroughput(),
            'average_latency_ms' => $this->calculateLatency(),
            'queue_depth' => $this->queue->size(),
            'worker_utilization' => $this->getWorkerUtilization()
        ]);
    }
}
```

**Integration Pattern Excellence**:
```php
// Robust Pipeline Integration
final class PipelineIntegrationManager
{
    public function ensureReliableIntegration(): void
    {
        // Circuit breaker for queue dispatch
        $this->circuitBreaker->protect(function() {
            $this->dispatchToQueue();
        });

        // Retry logic with exponential backoff
        $this->retryManager->withStrategy(
            ExponentialBackoffStrategy::create()
                ->withMaxAttempts(3)
                ->withBaseDelay(Duration::fromMilliseconds(100))
        );

        // Health monitoring integration
        $this->healthMonitor->addCheck(
            new PipelineIntegrationHealthCheck(
                $this->scheduler,
                $this->queue
            )
        );
    }
}
```
