How do I group consumers in RabbitMQ?
<p>We are writing mail sync system, and we use RabbitMQ for that. Every producer pushes mails ids, then consumer gets ids and insert mails to db. In situation when we have 100 consumers (for example) and producers will generate ids too fast, every consumer will get ids and will use api to get mails, so then will be exception about limit of concurrent request to the api. </p>

<p>Сan we limit consumer for each producer ( for example, if max 3 consumer will be receive ids of one producer, then next 3 will receive from other one, and so on) ?</p>
