[rabbitmq-discuss] How to handle failover without losing messages if one of RabbitMQ node crashes in cluster

[Jaymin Shah]

Hi,


I have RabbitMQ cluster (2 instances of v2.6) on EC2. With this setup I am
able to process around 51K/s messages.


I have one exchange and 3 queues bound to each instance totaling to 6
consumers and 3 producer each sending messages to each instance totaling to
6 producers. Note that queue is not durable.


I am expected to validate if one of instance in cluster goes down then would
I be losing messages? If yes then what could be done to avoid that. We tried
durable queues but it does not give desired performance due to very high IO
and that too on virtual environment like EC2.


regards,

Jaymin
