Context:

• given:
  • Optimize runs already for a while and has imported a lot of data
• when:
  • I configure a time to life (TTL) for the data
• then:
  • all data that is older then the defined data, is going to be removed

AT:

• Configuration should be disabled as default
• Time to live period (TTL) from which process instances should get cleaned up can be defined for all definitions with one property, additionally process definition keys can overwrite this config
• TTL property refers to the process instance end time/date
• For configuring the TTL we should use the https://en.wikipedia.org/wiki/ISO_8601#Durations format as done in the engine
• Cleanup job Start Time can be configured in configuration. Job runs periodically automatically based on this configuration.
• As User I can decide if want to delete all data related to the process or only variables
• If there is a specific configuration present for a process definition key that is not present in the database the cleanup run should get aborted and an error logged, to avoid loosing data due misconfiguration
