rabbitmq - prefetch count per consumer

I would like to use the node-amqp library the create multiple consumers for RabbitMQ, but I can't understand whether the prefetch-count option refers to count per consumer or not. I would like each consumer to have its own prefetch count that does not depend on other consumers.

Thanks.

Can be per single consumer but can be set for multiple consumers at once. Just look for title Example - single consumer here. So AMQP supports it. I'm not sure for the library you've mentioned but on official java lib it is like that - transparent towards AMQP's basic.qos method. Also from the aforementioned link

Note that the default value for the global flag is false in most APIs

and for rabbitmq when global==false

prefetch_count is applied separately to each new consumer on the channel

so you would need to find out how it's implemented in that librabry.

Additionaly consider using amqp.node library, since this one is used on rabbimtq tutorials. (EDIT I only now see that Derick Bailey has mentioned that already.)
