Work Queues: Fair Dispatch
Implement work queues to distribute tasks among multiple consumers using a round-robin dispatch strategy. Learn how to process time-consuming tasks asynchronously.
Meet Work Queues
Welcome to Work Queues! In distributed systems, you often have tasks that take time to complete, like processing an image or generating a report.
Work Queues are a pattern that helps distribute these time-consuming tasks among multiple workers (consumers) efficiently, preventing any single worker from getting overloaded.
Why Use Work Queues?
Imagine you have many jobs to do, but only one employee. If all jobs go to that single employee, they'll get overwhelmed and tasks will pile up.
- Load Balancing: Work queues allow you to add more workers to share the load.
- Asynchronous Processing: The producer doesn't wait for a task to finish, it just adds it to the queue.
- Reliability: If one worker fails, others can pick up tasks.
