History Cleanup

We have the following in our bpm-platform.xml:

<properties>
  <property name="history">full</property>
  <property name="databaseSchemaUpdate">true</property>
  <property name="authorizationEnabled">true</property>
  <property name="jobExecutorDeploymentAware">true</property>
  <property name="jobExecutorActivate">true</property>
  <property name="defaultNumberOfRetries">1</property>
  <property name="defaultSerializationFormat">application/json</property>
  <property name="defaultUserPermissionNameForTask">TASK_WORK</property>
  <property name="historyCleanupBatchWindowStartTime">00:01</property>
  <property name="historyCleanupBatchWindowEndTime">23:59</property>
  <property name="historyCleanupBatchSize">1</property>
  <property name="historyCleanupBatchThreshold">0</property>
</properties>

But unfortunately we don’t see any process instances being cleaned up. historyTimeToLive is set to 1 day. We’re using version 7.7.3.

Hi @c.biever,

Could you please check the job log table in the database and attach it here. If something went wrong with the history cleanup there should be indicators for it.

I am curious about your decision to configure historyCleanupBatchSize to 1, any reasoning behind this or you are just testing?

Best regards,
Yana

Hallo Yana,

Sorry for the late reply. The chosen numbers are just for testing. In the meantime we have opened an issue (SUPPORT-3695) which contains a small test project.

Hallo Yana,

By observing over a longer time period and the help of Camunda Support we are confident that the issue is resolved.
