A sandbox for the RabbitMQ Java client
You may change the number of nodes connected to RabbitMQ and number of publisher and consumer threads on each node. A node holds two connections to the message broker - one for publishing, another for consuming, and creates a channel for each publisher/consumer thread.
Publishing threads work without any delays, as fast as they can. The only work that they do is to convert Long
timestamps into byte arrays. Consuming threads do the opposite conversion and a little bit more work - appending
received timestamps into a ConcurrentLinkedDeque.
It is expected that a rabbitmq-server is started on the localhost:5672.
