What happens to messages that end up stuck in queues? Do they just disappear? What is the best way to prevent messages from being dropped silently, without warning? In this chapter, we will answers these questions thoroughly, looking in detail at message time to live (TTL) and dead-letter exchanges and queues. This chapter will also cover how the broker should react if a message cannot be routed to a specific queue using a mandatory flag. Additionally, the chapter will explain policies and the default exchange.
Expect to learn important information about the following topics:
- Handling dead letters
- Making delivery mandatory
