RabbitMQ: Direct Exchange vs Fanout Exchange

I've been trying to use RabbitMQ and faced the following question (very similar to this one: Topic Exchange vs Direct Exchange in RabbitMQ).

I need to intensively broadcast something around 800 types of messages (so there will be many consumers for each message type) and I wonder which of the following approaches is better:

  1. Create one direct exchange where messages will be sent with a routing key (message type name) and every consumer will be connected to it with a temporary queue bound with a corresponding routing key. (Because there is no complex routing keys like 'key1.key2.*' I decided not to use topic exchange).

  2. Create a fanout exchange for each message type.

I've read very good article about performance issues - ROUTING TOPOLOGIES FOR PERFORMANCE AND SCALABILITY WITH RABBITMQ but I'm new to RabbitMQ and just want to get some more best practices advice.

Go with the routing key, it will be simpler and more efficient :)
