## Rate Limit Queue Execution

Set rate limits on a queue to control how many workflows start in a given period. Rate limits are global across all DBOS processes.

**Incorrect (no rate limiting):**

```typescript
const queue = new WorkflowQueue("llm_tasks");
// Could send hundreds of requests per second to a rate-limited API
```

**Correct (rate-limited queue):**

```typescript
const queue = new WorkflowQueue("llm_tasks", {
  rateLimit: { limitPerPeriod: 50, periodSec: 30 },
});
```

This queue starts at most 50 workflows per 30 seconds.

**Combining rate limiting with concurrency:**

```typescript
// At most 5 concurrent and 50 per 30 seconds
const queue = new WorkflowQueue("api_tasks", {
  workerConcurrency: 5,
  rateLimit: { limitPerPeriod: 50, periodSec: 30 },
});
```

Common use cases:
- LLM API rate limiting (OpenAI, Anthropic, etc.)
- Third-party API throttling
- Preventing database overload
