摘要： Techniques are disclosed for a workflow engine performing a checkpoint phase to determine a result of a merge of workflow updates. The techniques may include the workflow engine determining to allow parallel execution of updates of a workflow. The workflow engine may receive first checkpoint data associated with a first update. The workflow engine may also receive second checkpoint data associated with a second update. The workflow engine may initiate the checkpoint phase that includes comparing one or more data elements of the first checkpoint data with respective data elements of the second checkpoint data; and determining the result of the merge of the workflow updates based on the comparing. The workflow engine may then complete the checkpoint phase and transmit the result to at least one user device for presentation.
