+title: HTTL required
+description: HTTL (History Time To Live) is required in BPMN, DMN, and CMMN models for History Clean up.
---
+Each execution of a model resource (BPMN, DMN, and CMMN) generates historic data during execution that is stored in the database. 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. The referenced escalation must have a defined escalation code. To fix this problem, open the **Escalation** group in the properties panel, select or create an escalation, and specify its escalation code.
-
-Camunda 8.2 and later support catch-all events and do not require an escalation reference.
