[rabbitmq-discuss] 100,000+ connections

[Chris Eineke]

Hello everyone,

I'm trying to find out what broker setup could support 100,000+ concurrent 
clients with 20-30 queues per client, with numbers steadily increasing over 
time. We would be sending mostly small messages (max. 4KiB, non-binary). One 
pitfall is that clients aren't guaranteed to be online 100% of the time, so 
we have to be able to deal with issues related to intermittent connectivity.

So far my idea is to install a RabbitMQ broker on each client and use the 
federation plugin to connect the client-side brokers to the server-side 
broker/cluster. Has RabbitMQ been exercised with a large number of 
federated queues/exchanges? Has anybody reported their configuration 
settings and performance numbers with related set-ups?

Best regards,
  Chris
