Hi,

I am writing to provide an update regarding our current capability to track process variable history in our Kogito implementation.

After reviewing our architecture and database schema, I’ve confirmed that we do not have a VariableInstanceLog equivalent or any similar table for auditing process variables. We are not using kogito data index.


Right now we are using kogito 10.1.0, quarkus 3+ version and able to see only these tables

  • business_key_mapping
  • correlation_instances
  • flyway_schema_history
  • jbpm_user_tasks
  • jbpm_user_tasks_admin_groups
  • jbpm_user_tasks_admin_users
  • jbpm_user_tasks_attachments
  • jbpm_user_tasks_comments
  • jbpm_user_tasks_deadline
  • jbpm_user_tasks_deadline_timer
  • jbpm_user_tasks_excluded_users
  • jbpm_user_tasks_inputs
  • jbpm_user_tasks_metadata
  • jbpm_user_tasks_outputs
  • jbpm_user_tasks_potential_groups
  • jbpm_user_tasks_potential_users
  • jbpm_user_tasks_reassignment
  • jbpm_user_tasks_reassignment_timer
  • kie_flyway_history_jbpm_user_task_storage
  • kie_flyway_history_runtime_persistence
  • process_instances 

Please let me know if any one have any idea on this. 


Regards
Santosh

Process variable logs are maintained in 'process_instance_variable_log' table. For that add data-audit add-on:

<dependency>
<groupId>org.kie</groupId>
<artifactId>kogito-addons-quarkus-data-audit-jpa</artifactId>
</dependency>
