[nova][dev] Stein blueprint burndown chart
Hey all, We have just wrapped up RC1 and I have a burndown chart [1] of blueprints [2] for the Stein cycle to share. I sent a similar email after we released Rocky last cycle [3]. I generated data for this chart throughout the cycle using a script I have proposed to add to the nova-specs repo [4]. Comparing final numbers to Rocky -------------------------------- Max approved for Rocky: 72 Max approved for Stein: 49 Final completed for Rocky: 59 Final completed for Stein: 29 Our completion percentage of approved blueprints in Rocky was 81.9% and in Stein it was 59.2%. We had a significant drop in completion percentage from last cycle. We approved many more blueprints than we completed. Comparing the release note prelude from Rocky [5] to Stein [6], I think we had an increase in larger and more complex user-impacting features implemented this cycle than last cycle. Throughout the cycle, we also had the placement extraction happening, which was a substantial amount of work not represented by a blueprint. Finally, many of the approved blueprints which were not completed were also larger and more complex features (NUMA-aware live migration, SRIOV live migration, cross-cell resize, detach/attach of root volume, just to name a few). I think we completed an impressive amount of work this cycle and I'm proud of how many user-impacting features we released.

Thanks Melanie, that's really interesting insights as always. Regards, -- Thierry Carrez (ttx)
