Apache KIE Examples is a curated monorepo of runnable example applications for the Kogito platform, which unifies Drools rules, jBPM processes, DMN decisions, and PMML predictions into cloud-native services. The repository contains 100+ standalone Maven and Gradle modules, each a self-contained Quarkus or Spring Boot microservice demonstrating a specific Kogito capability: BPMN process orchestration with user tasks and timers, DMN decision tables, DRL rule units, PMML scoring, Kafka/CloudEvents event-driven flows, transactional outbox with Debezium, persistence via MongoDB/PostgreSQL/Infinispan, Keycloak OIDC security, Prometheus/Grafana monitoring, and OpenShift/Kubernetes deployment. The dominant pattern is parallel Quarkus and Spring Boot implementations of the same example, plus Gradle build variants, so engineers can compare runtime behavior across stacks.
