Memastikan keandalan pesan (tidak kehilangan pesan) di RabbitMQ melibatkan antrian yang tahan lama, pesan persisten, acknowledgments, dan publisher confirms. Memahami mekanisme-mekanisme ini penting untuk membangun messaging yang andal dan dapat bertahan terhadap kegagalan.
Lapisan keandalan
To ensure messages aren't lost, address each point of potential loss:
1. PUBLISHING → did the message reach the broker?
2. STORAGE → does the message survive a broker restart/crash?
3. CONSUMPTION → is the message processed before being removed?
→ reliability requires handling ALL three
