RabbitMQ Overview, Installation Guide, and Delayed Message Implementation

RabbitMQ is a lightweight, open‑source AMQP broker offering reliable, flexible routing, clustering, and multi‑protocol support; it can be installed via Homebrew, Windows installers, or source on CentOS, and, using the rabbitmq_delayed_message_exchange plugin, Spring Boot applications can configure custom exchanges, queues, and send delayed messages with an x‑delay header.

Implementing a Distributed Delayed Message Queue in Go Using Redis

Implementing a distributed delayed message queue in Go with Redis uses a List for ready jobs and a Sorted Set for delayed jobs, periodically migrating expired entries atomically via Lua or transactions, providing O(1) enqueue/dequeue performance, retry support, and scalable concurrency for multi‑instance systems.
