# Celery Task Routing Strategies Skill

This skill provides comprehensive templates, scripts, and patterns for implementing advanced task routing and queue management in Celery applications, including priority queues, topic-based routing, and worker-specific queue assignments.

## Overview

Effective task routing is crucial for:

1. **Performance Optimization** - Route compute-intensive tasks to dedicated workers
2. **Priority Management** - High-priority tasks bypass slower queues
3. **Resource Isolation** - Separate critical operations from background jobs
4. **Scalability** - Independent scaling of different task types

This skill covers routing with RabbitMQ, Redis, and custom broker configurations.

## Available Scripts

### 1. Test Routing Configuration

**Script**: `scripts/test-routing.sh <config-file>`

**Purpose**: Validates routing configuration and tests queue connectivity

**Checks**:
- Broker connectivity (RabbitMQ/Redis)
- Queue declarations
- Exchange configurations
- Routing key patterns
- Worker queue bindings
- Priority queue setup

**Usage**:
```bash
# Test routing configuration
./scripts/test-routing.sh ./celery_config.py

# Test with custom broker URL
BROKER_URL=amqp://user:password@localhost:5672// ./scripts/test-routing.sh ./celery_config.py

# Verbose output
VERBOSE=1 ./scripts/test-routing.sh ./celery_config.py
```

**Exit Codes**:
- `0`: All routing tests passed
- `1`: Configuration errors detected
- `2`: Broker connection failed

### 2. Validate Queue Configuration

**Script**: `scripts/validate-queues.sh <project-dir>`

**Purpose**: Validates queue setup across application code

**Checks**:
- Task decorators use valid queues
- No hardcoded queue names (use config)
- All queues defined in routing configuration
- Priority settings are valid (0-255)
- Exchange types match routing patterns
- Worker configurations reference valid queues

**Usage**:
```bash
# Validate current project
./scripts/validate-queues.sh .

# Validate specific director
