In some cases, you’ll need to retry or cancel many workflow instances at once. Operate also supports this type of operation.
Imagine a case where many workflow instances have an incident caused by the same issue. At some point, the underlying problem will have been resolved (for example, maybe a microservice was down for an extended period of time then was brought back up).
But even though the underlying problem was resolved, the affected workflow instances are stuck until they are “retried”.
Let's create a selection in Operate. A selection is simply a set of workflow instances on which you can carry out a batch retry or batch cancellation. To create a selection, check the box next to the workflow instances you'd like to include, then click on the blue
Apply Operation on N Instances button.
Then select the operation you want to apply.
After confirmation you can see the Operations panel with current status of all operations.
