I'd like to run tasks in Plone which take long time to complete (minutes). For the duration of the task I could present a progress bar using AJAX.
Are there any ready Plone libraries / add-ons which allow you to serialize task to pieces and give AJAX status report automatically, without need to manually split and maintain the long running task state on the server?
E.g.
You start the task with start() method
Task gives status with getStatus() or similar
Framework will handle making the task asynchronous and has front-end code to follow the task status
