In a web application, task queuing is a technique that optimizes the processing of tasks by decoupling time-consuming or resource-intensive operations from the main application flow, allowing for faster response times and improved responsiveness. Task queuing reduces request/response time by delegating tasks to dedicated workers independently of the main application flow, enabling parallel processing and ensuring resource isolation. It also facilitates horizontal scalability and fault tolerance by allowing multiple workers to process queued tasks simultaneously. Laravel provides tools to manage and scale workers efficiently. Queued tasks can be retried in case of failures, reducing the risk of data loss or service disruptions. The technique is essential for optimizing the performance of web applications and ensuring a better user experience.
