Part2 Rabbitmq Best Practice For High Performance
- RMQ queues are single-threaded, meaning one queue is limit by performance of single core
- Performance tuning recommendations:
- Have multiple queues which will be distributed to multiple nodes after rebalancing
- HA (quorum in new rmq version) increases availability but affects performance due to messages replication
- Monitor rmq nodes load, in case it's not even trigger rebalance
- Rebalance
#queues can be balances with this command
$ rabbitmq-queues rebalance quorum
#then the major queues can be balanced with pattern
$ rabbitmq-queues rebalance quorum --queue-pattern "mmp.queue_quorum.[1-5]+"
#afterwards it can be checked with this on which node a specific queueu is running
$ rabbitmq-queues quorum_status --vhost growth_rabbitmq_stg_vhost mmp.queue_quorum.1
