Hello everyone! Earlier topic of unconditional migrations was discussed in emails by me and Salvatore. On summit there was a small meeting on which was discussed this topic and some others. I haven't participated in this meeting but member of my team Eugene was there instead of me and told me what was decided to do. The idea is to create some methods that will check current table state: - if it exists or not - if all necessary changes have been made or not. (All changes are checked from the very beginning till Icehouse) I was inspired of this idea and make some notes about that. They are shown there https://docs.google.com/document/d/10p6JKIQf_rymBuNeOywjHiv53cRTfz5kBg8LeUCeykI/edit?usp=sharingand a test change that will show how this is going to work https://review.openstack.org/93690. The organizer of all this work is Henry Gessau. Now he is working on bp on this topic. I look forward to any comments about my notes and my test changes.
