Dead Letter Exchanges
Symfony and RabbitMQ
Dead Letter Exchanges
• Delayed Messages (Events)
• Retries
• Errors processing
• etc.
Symfony and RabbitMQ
Dead Letter Exchanges
• The message is rejected
(basic.reject or basic.nack)
with requeue=false
• The TTL for the message expires;
• The queue length limit is exceeded.
Symfony and RabbitMQ
Dead Letter Exchanges
Symfony and RabbitMQ
Dead Letter Messages
x-death header:
queue – name of the queue the message was in before
reason – rejected | expired | maxlen
time – timestamp the message was dead lettered
exchange – the exchange the message was published to
routing-keys – the routing keys the message was published with.
original-expiration – the original expiration message property
Symfony and RabbitMQ
Delayed Pattern
MSG ExchangeQ1
TTL = 60000

More Queues = Better
Queue lives in 1 Eralng process
Symfony and RabbitMQ
Per-Message TTL
vs
Per-Queue TTL
