Hello everyone! I was looking at the topic of usage taskflow persistence and jobboard in Octavia [1]. I created a simple PoC to check what should be done to enable this functionality [2] . >From what I see, taskflow expects that data, which will be stored in persitence backend/jobboard backend, is a dict or an object easily converted to dicts [3] (error [3.1]) Also functions that creates flow should be importable [4] (error [4.1]). These two points lead to refactor required for Octavia to enable taskflow persistence and jobboard: 1) Convert data which is passed between flows in dicts, at this moment it is db objects with links to other db objects. 2) Create importable flow functions. As far as I see the only OpenStack project which adapted taskflow persistence is poppy [5] I'm looking for taskflow expect to take a look at all this and give some comments - whether I am correct or missing something. Thank you for your time in advance!
