Request/reply (RPC) RabbitMQ मा synchronous-शैली request-response communication सक्षम गर्छ messaging प्रयोग गरेर — एक client ले request पठाउँछ र reply queue मार्फत response पाउँछ, correlation ID प्रयोग गरेर responses लाई requests सँग मेल खाइ दिन। यो service-to-service calls को लागि उपयोगी pattern हो।
RabbitMQ मा RPC कसरी काम गर्छ
RPC pattern over messaging:
1. CLIENT sends a REQUEST message, including:
→ a REPLY-TO queue (where the response should go)
→ a CORRELATION ID (unique ID to match the response to this request)
2. SERVER (consumer) processes the request and sends a RESPONSE to the reply-to queue,
including the same CORRELATION ID
3. CLIENT receives the response from its reply queue, matches it by CORRELATION ID →
pairs the response with the original request
→ request-response over async messaging
