RabbitMQ at Scale, Lessons Learned

Operating RabbitMQ at large scale comes with it's own set of challenges. This talk will take you on the journey Cisco faced with operating a large (800+ node) environment inside a single RabbitMQ cluster. We will share the pains, lessons learned and best practices to stabilize and improve messaging performance and reliability.

This talk includes:

  • OpenStack service configurations related to messaging
  • Kombu driver enhancements
  • Considerations when virtualizing the control plane, and how default network buffer settings can be insufficient.
  • RabbitMQ Erlang arguments related to TCP_USER_TIMEOUT and their impact
  • The overhead of Queue Mirroring
  • Kernel level network settings to improve RabbitMQ failover and provide faster service re-connect
  • Alerting and Monitoring RabbitMQ
  • Recovering from a cluster partition
  • Architectural decisions 

What can I expect to learn?

Attendees will walk away with best practices and configurations they can make to improve the reliabilty and perfomance of messaging in OpenStack.
