History Service Variable Update

[boulif18]

I would like modify variableUpdates with historyService in JAVA.

I can gather all variable of tasks of a process instance


List<HistoricTaskInstance> historicTasks = historyService.createHistoricTaskInstanceQuery().processInstanceId(processInstanceId).list();
HashMap<String, List<HistoricDetail>> historicTaskDetails = new HashMap<String, List<HistoricDetail>>();
      for (HistoricTaskInstance historicTask : historicTasks) {
         historicTaskDetails.put(historicTask.getId(), historyService.createHistoricDetailQuery().taskId(historicTask.getId()).list());
      }
   
      for(Entry<String, List<HistoricDetail>> entry : historicTaskDetails.entrySet()) {
          key = entry.getKey();
          List<HistoricDetail> listTaskDetail = entry.getValue();
          for (int iteration = 0; iteration<listTaskDetail.size(); iteration++) {
             HistoricVariableUpdate historicVariableUpdate = (HistoricVariableUpdate) listTaskDetail.get(iteration);
             variableName = historicVariableUpdate.getVariableName();
          }
      }

How can i modify an historicVariableUpdate ?

Thanks

You can't. At least not with the API. The idea is that history = audit data, and audit data can't be changed.

Of course, you can always add your own custom query that allows this.

Are those audit data to be part of elasticsearch ? how to do we stop certain data to be stored/considered as audit data?

Elasticsearch is used in the enterprise product (did't get that from your original question). It's used for analytics only there, not for audit. All the audit data remains in the database.
