Seeking Advice on RabbitMQ Migration Strategies

[tafisa]

Hello everyone.

I'm currently exploring RabbitMQ migration options and would appreciate insights from the community. Specifically, I'm interested in strategies for migrating from classic queues to quorum queues. I understand this transition can enhance data integrity and fault tolerance, but what are the practical steps involved?

How do you handle message migration during the RabbitMQ migration process? Are there tools or best practices that can facilitate a smooth transition without significant downtime? Additionally, has anyone used shovel plugins or blue-green deployments for this type of migration, and what lessons did you learn?

Migrating from classic queues to quorum queues involves several practical steps. First, create quorum queues in parallel rather than replacing classic queues immediately. During the RabbitMQ migration, the Shovel plugin is commonly used to replicate messages from classic queues to quorum queues safely, allowing ongoing consumption without data loss. A blue-green deployment strategy can help: deploy consumers to quorum queues while keeping classic queues active, then switch over once everything is validated. Key best practices include testing in a staging environment, monitoring queue metrics, starting with low-traffic queues, and planning for the higher overhead of quorum queues.
