Message Queues & Events
Implement asynchronous communication between services using message queues and event-driven patterns.
Why Asynchronous Communication?
In microservices, different parts of your application often need to communicate. Sometimes, they don't need an instant reply or to wait for each other to finish tasks.
Asynchronous communication means services can send messages and continue their work without waiting for a response. This improves performance, responsiveness, and overall system reliability.
What are Message Queues?
A message queue is like a temporary storage buffer for messages. Imagine a post office box where services can drop off and pick up mail.
- One service (the producer) sends a message.
- Another service (the consumer) retrieves and processes it later.
This pattern helps services avoid direct, real-time dependencies.
