## 📈 Scaling Strategy
|
||||
|
||||
### When to Scale
|
||||
- Response time > 2 seconds
|
||||
- CPU usage consistently > 80%
|
||||
- Memory usage consistently > 80%
|
||||
- Queue backlog growing
|
||||
- Error rate increasing
|
||||
- During peak usage times
|
||||
|
||||
### Horizontal Scaling
|
||||
```bash
|
||||
# Add more workers to docker-compose.prod.yml
|
||||
# Example: 2 extra send workers
|
||||
|
||||
services:
|
||||
celery_worker_send_1:
|
||||
# existing config
|
||||
|
||||
celery_worker_send_2:
|
||||
# duplicate and modify
|
||||
container_name: tg_autoposter_worker_send_prod_2
|
||||
|
||||
celery_worker_send_3:
|
||||
# duplicate and modify
|
||||
container_name: tg_autoposter_worker_send_prod_3
|
||||
```
|
||||
|
||||
### Vertical Scaling
|
||||
- Increase docker resource limits
|
||||
- Increase database memory
|
||||
- Increase Redis memory
|
||||
- Optimize queries and code
|
||||
|
||||
### Database Scaling
|
||||
- Read replicas for read-heavy workloads
|
||||
- Connection pooling
|
||||
- Query optimization
|
||||
- Caching layer (already implemented)
|
||||
- Partitioning large tables (if needed)
|
||||
|
||||
## 📞 Support & Escalation
|
||||
|
||||
### Support Channels
|
||||
- GitHub Issues for bugs
|
||||
- GitHub Discussions for questions
|
||||
- Email for critical issues
|
||||
- Slack/Discord channel (optional)
|
||||
|
||||
### Escalation Path
|
||||
1. Check logs and metrics
|
||||
2. Review documentation
|
||||
3. Search GitHub issues
|
||||
4. Ask in GitHub discussions
