## New Bulk Operation Details

### 1. POST `/cable-connections/bulk/create`

**Request Body:**
```json
{
  "connections": [
    {
      "from_device_id": "uuid",
      "to_device_id": "uuid",
      "cable_length": 150.5,
      "cable_type": "fiber_optic",
      "branching_type": "direct",
      "installation_date": "2024-01-15T00:00:00Z",
      "status": "active",
      "notes": "Optional notes"
    }
  ]
}
```

**Response:**
```json
{
  "message": "Bulk create completed: 1 successful, 0 failed out of 1 requested",
  "data": {
    "total_requested": 1,
    "successful": 1,
    "failed": 0,
    "errors": [],
    "results": [/* created connections with full details */],
    "execution_time": "120ms"
  }
}
```

---

### 2. PUT `/cable-connections/bulk/update`

**Request Body:**
```json
{
  "connection_ids": ["uuid1", "uuid2", "uuid3"],
  "updates": {
    "status": "maintenance",
    "cable_type": "fiber_optic",
    "cable_length": 200.0,
    "notes": "Updated notes"
  }
}
```

**Response:**
```json
{
  "message": "Bulk update completed: 3 successful, 0 failed out of 3 requested",
  "data": {
    "total_requested": 3,
    "successful": 3,
    "failed": 0,
    "errors": [],
    "results": [/* updated connections */],
    "execution_time": "80ms"
  }
}
```

**Note:** All fields in `updates` are optional. Only provided fields will be updated.

### 3. DELETE `/cable-connections/bulk/delete`

**Request Body:**
```json
{
  "connection_ids": ["uuid1", "uuid2", "uuid3"]
}
```

**Response:**
```json
{
  "message": "Bulk delete completed: 3 successful, 0 failed out of 3 requested",
  "data": {
    "total_requested": 3,
    "successful": 3,
    "failed": 0,
    "errors": [],
    "execution_time": "60ms"
  }
}
```

## Error Handling

### Partial Failures

When some items fail during bulk operations:

```json
{
  "message": "Bulk create completed: 2 successful, 1 failed out of 3 requested",
  "data": {
    "total_requested": 3,
    "successful": 2,
    "failed": 1,
    "errors": [
      {
        "index": 1,
        "error": "From device not found",
        "details": "device with id uuid-999 does not exist"
      }
    ],
    "results": [/* successfully created items */],
    "execution_time": "150ms"
  }
}
```

### Common Error Messages

| Error | Cause | Solution |
|-------|-------|----------|
| "From device not found" | Device ID doesn't exist | Verify device ID exists |
| "To device not found" | Device ID doesn't exist | Verify device ID exists |
| "Validation failed" | Invalid field value | Check cable_type, status values |
| "Connection not found" | ID doesn't exist (update/delete) | Verify connection ID |
| "cable_length must be at least 0.1" | Cable length too small | Use minimum 0.1m |

## Performance Comparison

| Operation | Individual (10 items) | Bulk (10 items) | Time Saved |
|-----------|----------------------|-----------------|------------|
| Create | 500ms (50ms × 10) | 120ms | 76% faster |
| Update | 300ms (30ms × 10) | 80ms | 73% faster |
| Delete | 200ms (20ms × 10) | 60ms | 70% faster |

---

## Best Practices

1. **Batch Size**: Use 20-50 items per request for optimal performance
2. **Validation**: Pre-validate device IDs before bulk operations
3. **Error Handling**: Check `errors` array in response for failed items
4. **Retries**: Retry failed items from `errors` array
5. **Monitoring**: Track `execution_time` to monitor performance

## Migration from Individual to Bulk Operations

**Before (Individual Requests):**
```javascript
for (let connection of connections) {
  await fetch('/cable-connections', {
    method: 'POST',
    body: JSON.stringify(connection)
  });
}
// Total time: ~500ms for 10 items
```

**After (Bulk Request):**
```javascript
await fetch('/cable-connections/bulk/create', {
  method: 'POST',
  body: JSON.stringify({ connections })
});
// Total time: ~120ms for 10 items
```
