What is Message Queue?
A system that stores messages between services, ensuring they are processed even if the receiving service is busy.
Why It Matters
Message queues prevent data loss during traffic spikes and allow services to process work at their own pace.
Real-World Example
Email notifications are added to a queue and sent one by one, even if thousands are triggered at once.
“Understanding terms like Message Queue matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
