Do microservices dream about CQRS ES, Kafka Stream and BPMN ?
summary
Quicksign migrates a monolith to a Kubernetes microservices platform that combines Camunda BPMN for long running processes (5 minutes to 3 months) with a Kappa CQRS‑ES backbone on Kafka Streams and RocksDB to produce fully generated HATEOAS REST APIs. Platform processes millions of subscriptions per year at 70% growth and emits 1.3M audit entries/day, requires at‑least‑once delivery and sequential per‑aggregate processing achieved with a composite key + custom partitioner, and uses interactive queries for low‑latency reads.
