Some message loss is acceptable in order to limit the maximal message latency. Could any one inform me how to configure rabbitmq to let it drop some messages when the latency is too high or the queue is reached to a maximum value.
You can tell rabbit to drop messages 'older than' something -
Also take a look at immediate flag to basic.publish (this will forbid
being published if it can't be delivered to a consumer immediately)
But it's your responsibility to ensure that messages are being consumed
fast enough. Queue.ttl and 'immediate' may help, but eventually
RabbitMQ is a queuing system constructed to queue messages - not lose
