Definition:Message Queue
A Message Queue is a buffer that stores asynchronous tasks for processing by background worker services.
Detailed Technical Explanation
Business Perspective
Message queues maintain website speed when users perform heavy actions like generating reports or uploading files.
Technical Perspective
Engineered using Redis BullMQ, RabbitMQ, or AWS SQS to handle background job retries and dead-letter queues.
Real-World Example
Pushing email receipt generation tasks to a message queue so the checkout API responds in under 100ms.
Common Architectural Mistakes
- ✗Missing Dead-Letter Queues: Failing to capture permanently failed jobs, causing silent task loss.
