General Overview

• ExRabbitPool creates a pool of connections to RabbitMQ
• each connection worker traps exits and links the connection process to it
• each connection worker creates a pool of channels and links them to it
• we spawn in the ConsumerSupervisor a given number of GenServers that are going to be our RabbitMQ consumers
• each consumer is going to get a channel out of the channel pool and is going to subscribe itself as a consumer via Basic.Consume using that channel

High Level Architecture

It is really similar to the architecture of buildex_poller in the sense that we need a pool of connections and channels to RabbitMQ and a pool of workers, in this case, RabbitMQ Consumers; this is because we also use ExRabbitPool which is our connection layer that both apps uses.
