# Local group rate limit

Sometimes it is required that different groups have different rate limits, this could be the case for example if a group represents a given user in the system, and depending on the user's quota or other factors we would like to have a different rate-limit for it.

You can use a local group rate limit, which would be used only for the specific group that have the rate-limit setup. For example:

```typescript
import { QueuePro, WorkerPro } from '@taskforcesh/bullmq-pro';

const queue = new QueuePro('myQueue', { connection });
const groupId = 'my group';
const maxJobsPerDuration = 100;

const duration = 1000; // duration in ms.
await queue.setGroupRateLimit(groupId, maxJobsPerDuration, duration);

const worker = new WorkerPro(
  'myQueue',
  async () => {
    // do something
  },
  {
    group: {
      limit: {
        // default rate limit configuration
        max: 1000,
        duration: 1000,
      },
    },
    connection,
  },
);
```

This code would set a specific rate limit on the group "my group" of max 100 jobs per second. Note that you can still have a ["default" rate-limit](/bullmq-pro/groups/rate-limiting.md) specified for the rest of the groups, the call to `setGroupRateLimit` will therefore allow you to override that rate-limit.

{% hint style="warning" %}
You must specify a default rate limit by passing group.limit option in each Worker instance. In this way, workers are allowed to check if groups are rate limited or not.
{% endhint %}
