Processing 1m msgs/CPU/GB of memory with Quarkus and MicroProfile ...
summary
VCStream is a data-integration platform built at Décathlon to connect legacy value-chain systems (ERP, AS/400) to the rest of the IT landscape. The talk explains how the team implemented VCStream using Quarkus and MicroProfile Reactive Messaging with Kafka to achieve very high message throughput (about 1 million messages per CPU per GB of memory) while keeping a simple, resilient, and fault-tolerant implementation; presenters show code and architecture diagrams and describe the performance optimizations they used.
