I was thinking about the trigger we need to consider. Actually we have to publish the blog after it's been reviewed and approved. In this case we can introduce two columns: isReviewed and isPublished. First, this pipeline will check if some articles unpublished and then if they are reviewed. If they are not published and reviewed, the generation will be triggered. What do you think?
