History time to live
Camunda 7 only
Each execution of a model resource (BPMN, DMN, and CMMN) generates historic data during execution that is stored in the database. In Camunda 7, history cleanup removes this historic data from the database based on a defined history time to live (HTTL).
From Camunda 7.20 onwards, you must configure HTTL in one of the following ways:
- Define HTTL per model directly in Desktop Modeler.
- Set a default HTTL via an engine configuration.
- Switch off the HTTL check via an engine configuration if history cleanup is not used.
History time to live not configured
In the screenshot above, note that the time to live must be defined under History cleanup in the properties panel.
