Over time, the users of the CSN increased rapidly and the workload of the system was increasing even more rapidly on a daily basis. It was estimated that this growth might cause issues with the single RabbitMQ broker instance, which essentially turned out to be a bottleneck.
That is why the team behind the CSN decided to introduce several new RabbitMQ instances installed on separate powerful servers and separate the queues from the v_events vhost on one node and the queues from the v_chat host on two other nodes:
