Taming the event chaos with a workflow engine

" summary

Flowable connects to Kafka (Confluent stack) and Spring Boot, consumes Avro events with Avro deserializers and starts or updates case models to correlate by orderId/customerId. Three external validators (fraud, inventory, order detail) publish validation results to a Kafka topic; a validator-aggregator stream waits ~5 minutes and marks orders validated or failed. On failure Flowable spawns a process with timers, history stored in DB, and a DMN table does DMN decision routing to lawyer groups. Deployment uses REST APIs and the open source engine; demo runs end‑to‑end.
