body: <p>I am looking for help on how to re-trigger the failed camunda workflows in effective way such as Batch..</p>
  
  <p>Here is the scenario details</p>
  
  <p>I have a camunda workflow which is triggered by service A via rest API. The workflow uses External task to implement the business logic to talk to service B . 
  If the workflow failed because of the transient errors in service B and those workflows will be failed. If the requests are 1 or 2, those can be re-triggered manually.
  But if the failed workflows are in order 10s or 100s, it will be cumbersome to do manually hence I am looking on help the options to address this..</p>
  
  <p>Are there are any better ways to re-trigger the failed camunda workflows either using Camunda UI or Rest APIs or any other options?</p>
  
  <p>Details  of the Camunda
