Pooling AMQP TLS connections in Elixir for high throughput and low latency

In the fast-paced, data-driven world of computing, reliable message brokers are critical for communication between services. One of the most widely adopted protocols in this domain is the Advanced Message Queuing Protocol (AMQP). As an open standard, AMQP has seen large-scale adoption across industries for its reliability, flexibility, and ability to handle both transactional and high-throughput workloads.

AMQP serves as the backbone for several popular messaging systems, most notably RabbitMQ, which has become a go-to solution for many enterprise clients. But what makes RabbitMQ shine in comparison to alternatives like Kafka, and why is it favored by a wide range of businesses, from startups to established enterprises?

The AMQP protocol is designed to ensure safe, guaranteed delivery of messages with features like message acknowledgments, routing, and delivery confirmations. Enterprises with complex architectures rely on these guarantees to keep their systems resilient. AMQP allows companies to achieve:

Transactional messaging: Ideal for financial systems or any environment where guaranteed message delivery is crucial.

Flexible message routing: Through its exchange types (direct, topic, fanout, headers), AMQP makes it easier to handle…
