The Camunda 7 History Cleanup removes this historic data from the database based on the HTTL (History Time To Live) defined. If using the History Cleanup in Camunda 7 the HTTL must be defined in one of the following ways: +- Define HTTL per model directly in the Camunda Modeller +- Set a default HTTL for the engine that is applied to all deployed model resources on the engine +- Switch off the HTTL check for the deployment if History Cleanup is not used -import MarkerGuideline from "@site/src/mdx/MarkerGuideline"; - -An [escalation event](../../../../bpmn/escalation-events/) must reference an escalation defined in the process.
