E-Commerce: Distributed Transactions + Search + RAG

Scenario

An e-commerce platform processes orders using OceanBase distributed transactions coordinated by RocketMQ transactional messages (with ordered delivery guarantees for inventory updates and delayed messages for order timeouts), then propagates real-time stock changes into RDS and Elasticsearch — powering product search with RAG-powered customer Q&A that always reflects current inventory and order state.

Q: How does the e-commerce architecture integrate distributed transactions with real-time search and AI answers? A: The platform processes orders using OceanBase distributed transactions coordinated by RocketMQ, then propagates real-time stock changes to RDS and Elasticsearch to power product search with RAG-enabled customer Q&A. This integration ensures that search results and AI responses always reflect current inventory and order states.
