Sidekiq

Sidekiq is a tool used by software applications to handle many tasks efficiently without slowing down the main system. It works by placing tasks—like sending emails or processing data—into a queue, then processing them in the background. This allows the main application to remain responsive and fast while tasks are completed asynchronously. Sidekiq is designed for high performance, managing large volumes of tasks simultaneously. It's typically used in web applications to improve user experience and system efficiency by offloading time-consuming or resource-intensive operations from the primary workflow.
