How does RabbitMQ handle cluster failover?
RabbitMQ uses a mechanism called mirrored queues to handle failover in a cluster. If a node fails, the mirrored queue on another node takes over.
What happens to messages during a failover?
Messages in transit may be lost if they are not acknowledged. However, messages in mirrored queues are preserved and can be processed by the new leader.
Can I configure RabbitMQ to minimize message loss?
Yes, you can configure RabbitMQ to use persistent messages and mirrored queues to minimize message loss during failover.
Are there any best practices for setting up RabbitMQ clusters?
Some best practices include using an odd number of nodes, ensuring network reliability, and regularly testing failover scenarios.
