High-volume transaction throughput is the backbone of modern retail and financial operations. However, directly querying an ERP database for every checkout event will quickly lead to CPU bottlenecks and API timeouts. This guide introduces event-driven microservices built on cloud platforms to offload integrations from the core database.
Event-Driven Architecture
By leveraging messaging brokers like RabbitMQ, Apache Kafka, or SAP Event Mesh, we can decouple message receipt from transaction processing, scaling throughput asynchronously.
