feat(workers): Concurrent task processing with resource-based backoff
Workers can now process multiple tasks concurrently (default: 3 max). Self-regulate based on resource usage - back off at 85% memory or 90% CPU. Backend changes: - TaskWorker handles concurrent tasks using async Maps - Resource monitoring (memory %, CPU %) with backoff logic - Heartbeat reports active_task_count, max_concurrent_tasks, resource stats - Decommission support via worker_commands table Frontend changes: - Workers Dashboard shows tasks per worker (N/M format) - Resource badges with color-coded thresholds - Pod visualization with clickable selection - Decommission controls per worker New env vars: - MAX_CONCURRENT_TASKS (default: 3) - MEMORY_BACKOFF_THRESHOLD (default: 0.85) - CPU_BACKOFF_THRESHOLD (default: 0.90) - BACKOFF_DURATION_MS (default: 10000) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

## Concurrent Task Processing (Added 2024-12)
|
||||
|
||||
Workers can now process multiple tasks concurrently within a single worker instance. This improves throughput by utilizing async I/O efficiently.
|
||||
|
||||
### Architecture

### Environment Variables
|
||||
|
||||
| Variable | Default | Description |
|
||||
|----------|---------|-------------|
|
||||
| `MAX_CONCURRENT_TASKS` | 3 | Maximum tasks a worker will run concurrently |
|
||||
| `MEMORY_BACKOFF_THRESHOLD` | 0.85 | Back off when heap memory exceeds 85% |
|
||||
| `CPU_BACKOFF_THRESHOLD` | 0.90 | Back off when CPU exceeds 90% |
|
||||
| `BACKOFF_DURATION_MS` | 10000 | How long to wait when backing off (10s) |
|
||||
|
||||
### How It Works
|
||||
|
||||
1. **Main Loop**: Worker continuously tries to fill up to `MAX_CONCURRENT_TASKS`
|
||||
2. **Resource Monitoring**: Before claiming a new task, worker checks memory and CPU
|
||||
3. **Backoff**: If resources exceed thresholds, worker pauses and stops claiming new tasks
|
||||
4. **Concurrent Execution**: Tasks run in parallel using `Promise` - they don't block each other
|
||||
5. **Graceful Shutdown**: On SIGTERM/decommission, worker stops claiming but waits for active tasks
|
||||
|
||||
### Resource Monitoring
|
||||
|
||||
```typescript
|
||||
// ResourceStats interface
|
||||
interface ResourceStats {
|
||||
memoryPercent: number; // Current heap usage as decimal (0.0-1.0)
|
||||
memoryMb: number; // Current heap used in MB
|
||||
memoryTotalMb: number; // Total heap available in MB
|
||||
cpuPercent: number; // CPU usage as percentage (0-100)
|
||||
isBackingOff: boolean; // True if worker is in backoff state
|
||||
backoffReason: string; // Why the worker is backing off
|
||||
}
|
||||
```
|
||||
|
||||
### Heartbeat Data
|
||||
|
||||
Workers report the following in their heartbeat:
|
||||
|
||||
```json
|
||||
{
|
||||
"worker_id": "worker-abc123",
|
||||
"current_task_id": 456,
|
||||
"current_task_ids": [456, 457, 458],
|
||||
"active_task_count": 3,
|
||||
"max_concurrent_tasks": 3,
|
||||
"status": "active",
|
||||
"resources": {
|
||||
"memory_mb": 256,
|
||||
"memory_total_mb": 512,
|
||||
"memory_rss_mb": 320,
|
||||
"memory_percent": 50,
|
||||
"cpu_user_ms": 12500,
|
||||
"cpu_system_ms": 3200,
|
||||
"cpu_percent": 45,
|
||||
"is_backing_off": false,
|
||||
"backoff_reason": null
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Backoff Behavior
|
||||
|
||||
When resources exceed thresholds:
|
||||
|
||||
1. Worker logs the backoff reason:
|
||||
```
|
||||
[TaskWorker] MyWorker backing off: Memory at 87.3% (threshold: 85%)
|
||||
```
|
||||
|
||||
2. Worker stops claiming new tasks but continues existing tasks
|
||||
|
||||
3. After `BACKOFF_DURATION_MS`, worker rechecks resources
|
||||
|
||||
4. When resources return to normal:
|
||||
```
|
||||
[TaskWorker] MyWorker resuming normal operation
|
||||
```
|
||||
|
||||
### UI Display
|
||||
|
||||
The Workers Dashboard shows:
|
||||
|
||||
- **Tasks Column**: `2/3 tasks` (active/max concurrent)
|
||||
- **Resources Column**: Memory % and CPU % with color coding
|
||||
- Green: < 50%
|
||||
- Yellow: 50-74%
|
||||
- Amber: 75-89%
|
||||
- Red: 90%+
|
||||
- **Backing Off**: Orange warning badge when worker is in backoff state
|
||||
|
||||
### Task Count Badge Details
|
||||
|
||||
```
|
||||
┌─────────────────────────────────────────────┐
|
||||
│ Worker: "MyWorker" │
|
||||
│ Tasks: 2/3 tasks #456, #457 │
|
||||
│ Resources: 🧠 65% 💻 45% │
|
||||
│ Status: ● Active │
|
||||
└─────────────────────────────────────────────┘
|
||||
```
|
||||
|
||||
### Best Practices
|
||||
|
||||
1. **Start Conservative**: Use `MAX_CONCURRENT_TASKS=3` initially
|
||||
2. **Monitor Resources**: Watch for frequent backoffs in logs
|
||||
3. **Tune Per Workload**: I/O-bound tasks benefit from higher concurrency
|
||||
4. **Scale Horizontally**: Add more pods rather than cranking concurrency too high
