# Queue Management

Queuety supports multiple named queues. Workers process one queue at a time, and queues can be paused and resumed independently.

## Named queues

Dispatch jobs to specific queues:

```php
use Queuety\Queuety;

Queuety::dispatch( 'send_email', $payload )->on_queue( 'emails' );
Queuety::dispatch( 'process_image', $payload )->on_queue( 'media' );
Queuety::dispatch( 'sync_data', $payload )->on_queue( 'sync' );
```

Run workers for each queue:

```bash
wp queuety work --queue=emails
wp queuety work --queue=media
wp queuety work --queue=sync
```

The default queue is `default`. If you don't specify a queue, jobs go there.

## Pause and resume

Pause a queue to stop workers from claiming new jobs. Jobs already being processed will finish, but no new jobs will be picked up.

```php
Queuety::pause( 'emails' );
Queuety::resume( 'emails' );
```

Check if a queue is paused:

```php
if ( Queuety::is_paused( 'emails' ) ) {
    // Queue is paused
}
```

Via CLI:

```bash
wp queuety pause emails
wp queuety resume emails
```

This is useful during deployments or maintenance windows when you want to temporarily stop processing without killing the worker.

## Queue statistics

Get job counts grouped by status:

```php
$stats = Queuety::stats(); // all queues
$stats = Queuety::stats( 'emails' ); // specific queue

// Returns: ['pending' => 12, 'processing' => 3, 'completed' => 150, 'failed' => 2, 'buried' => 1]
```

Via CLI:

```bash
wp queuety status
wp queuety status --queue=emails
```

## Buried jobs

List all buried jobs (failed after exhausting retries):

```php
$buried = Queuety::buried(); // all queues
$buried = Queuety::buried( 'emails' ); // specific queue
```

Retry them:

```php
Queuety::retry( $job_id );       // retry a specific job
Queuety::retry_buried();         // retry all buried jobs
```

## Purging completed jobs

Remove old completed jobs to keep the database clean:

```php
$count = Queuety::purge();     // uses QUEUETY_RETENTION_DAYS (default: 7)
$count = Queuety::purge( 30 ); // purge jobs older than 30 days
```

Via CLI:

```bash
wp queuety purge
wp queuety purge --older-than=30
```
