### 3.5 Data Cleanup Job

```typescript
// src/jobs/data-cleanup.job.ts

import { CronJob } from 'cron';
import { InvestmentRepository } from '../modules/investment/investment.repository';
import { logger } from '../utils/logger';

export class DataCleanupJob {
  private repository: InvestmentRepository;
  private job: CronJob;

  constructor() {
    this.repository = new InvestmentRepository();

    // Ejecutar semanalmente los domingos a las 03:00 UTC
    this.job = new CronJob('0 3 * * 0', () => this.run());
  }

  async run(): Promise<void> {
    logger.info('Starting data cleanup job');

    try {
      // Eliminar transacciones fallidas antiguas (>90 días)
      const deletedTransactions = await this.repository.deleteOldFailedTransactions(90);

      // Archivar cuentas cerradas antiguas (>365 días)
      const archivedAccounts = await this.repository.archiveOldClosedAccounts(365);

      // Limpiar logs antiguos (>180 días)
      // await this.repository.deleteOldLogs(180);

      logger.info('Data cleanup job completed', {
        deleted_transactions: deletedTransactions,
        archived_accounts: archivedAccounts,
      });
    } catch (error: any) {
      logger.error('Data cleanup job failed', { error: error.message });
      throw error;
    }
  }

  start(): void {
    this.job.start();
    logger.info('Data cleanup job scheduled: Sundays at 03:00 UTC');
  }

  stop(): void {
    this.job.stop();
  }
}
```

## 4. Inicialización en App

```typescript
// src/server.ts

import express from 'express';
import { JobManager } from './jobs/job-manager';
import { logger } from './utils/logger';

const app = express();
const jobManager = new JobManager();

// Iniciar servidor
const PORT = process.env.PORT || 3000;
const server = app.listen(PORT, () => {
  logger.info(`Server running on port ${PORT}`);

  // Iniciar jobs programados
  jobManager.start();
});

// Graceful shutdown
process.on('SIGTERM', () => {
  logger.info('SIGTERM received, shutting down gracefully');

  // Detener jobs
  jobManager.stop();

  // Cerrar servidor
  server.close(() => {
    logger.info('Server closed');
    process.exit(0);
  });
});
```

## 5. Configuración

### 5.1 Variables de Entorno

```bash
# Cron Jobs
ENABLE_CRON_JOBS=true
CRON_TIMEZONE=UTC

# Job Settings
DAILY_PERFORMANCE_CRON=30 0 * * *
MONTHLY_DISTRIBUTION_CRON=0 1 1 * *
WITHDRAWAL_PROCESSING_CRON=*/30 * * * *
DATA_CLEANUP_CRON=0 3 * * 0
```

## 6. Monitoreo y Logs

### 6.1 Logging

```typescript
// Logs detallados para cada job
logger.info('Job started', {
  job_name: 'DailyPerformanceJob',
  scheduled_time: '00:30 UTC',
  trigger: 'scheduled',
});

logger.info('Job completed', {
  job_name: 'DailyPerformanceJob',
  duration_ms: 12500,
  processed_items: 150,
  success_count: 148,
  error_count: 2,
});
```

### 6.2 Health Checks

```typescript
// Endpoint para verificar estado de jobs
app.get('/health/jobs', async (req, res) => {
  const jobStatuses = await jobManager.getJobStatuses();
  res.json(jobStatuses);
});
```

---

## 7. Testing

### 7.1 Manual Job Execution

```typescript
// Script para ejecutar job manualmente
// scripts/run-job.ts

import { JobManager } from '../src/jobs/job-manager';

const jobName = process.argv[2];

if (!jobName) {
  console.error('Usage: npm run job <JobName>');
  process.exit(1);
}

const jobManager = new JobManager();

jobManager
  .runJob(jobName)
  .then(() => {
    console.log(`Job ${jobName} completed successfully`);
    process.exit(0);
  })
  .catch((error) => {
    console.error(`Job ${jobName} failed:`, error);
    process.exit(1);
  });
```

```bash
# Ejecutar manualmente
npm run job DailyPerformanceJob
npm run job MonthlyDistributionJob
```
