Camunda 8 DMN vs Camunda 7 DMN – Key Differences
Decision Model and Notation (DMN) is a standards-based way to define, manage and automate business decisions that are part of your process automation solution. Both Camunda 7 and Camunda 8 support DMN, but there are important differences in how DMN is executed, modelled and integrated in the newer version. 🎯 1. Underlying Engine and Architecture One of the most fundamental differences between Camunda 7 and Camunda 8 — and therefore for DMN — is the engine architecture: Camunda 7 is built on the traditional Java-based process engine. Camunda 8 uses the Zeebe engine, designed for cloud-native, scalable execution of both BPMN and DMN models. This means that in Camunda 8, DMN execution is part of a distributed, horizontally scalable decision engine, whereas in Camunda 7 it runs in a monolithic embedded or server-based JVM. This foundational change influences performance and how decision models are deployed and scaled. 🧠2. Expression Language Used in DMN A key technical differe...
