Hello Everyone,

In this article we will see how important is to acknowledge the request being sent whether it got success or failed. we never got to know unless it is returning something. Acknowledgment ensures that a request was received, processed, or queued. Without it, the calling service may retry, fail, or behave unpredictably.

Significance

• Acting as a handshake — verifying delivery and allowing the system to maintain resilience, traceability, and reliability.
• In Human Communication, It maintains healthy relationships — personally and professionally — by reinforcing that the other person is heard and valued.
• For asynchronous messaging (e.g. Kafka, RabbitMQ), acknowledgment prevents message loss, duplicate processing, or back-pressure buildup.
