RabbitMQ in Action

Chapter 6. Writing code that survives failure

 

This chapter covers

• Understanding load balancing
• Installing and configuring HAProxy to load balance Rabbit
• Writing code that reconnects and intelligently survives failure

 

Building a RabbitMQ cluster to ensure availability and performance is only half the battle of ensuring a resilient messaging infrastructure. The other half is writing applications that expect node failure and knowing how to reconnect to the cluster when it happens. There are a number of strategies for handling reconnection to the cluster, but the one we’ll focus on is using a load balancer to handle node selection. By using a load balancer you not only reduce the complexity of the failure handling code in your apps, but you ...
