Hi all, tl;dr; Artifacts IS staying in Glance. 1. We had a nice discussion at the contributors' meet-up at the Vancouver summit this morning. After weighing in many possibilities and evolution of the Glance program, we have decided to go ahead with the Artifacts implementation within Glance program under the EXPERIMENTAL v3 API. Want to clarify a bit here. My understanding is: s/Artifacts/v3 API/g. That is to say, Artifacts is the technical implementation of the v3 API. This also means the v3 API is an objects API vs just an images API. We also had some hallway talk about putting the v1 and v2 APIs on top of the v3 API. This forces faster adoption, verifies supportability via v1 and v2 tests, increases supportability of v1 and v2 APIs, and pushes out the need to kill v1 API. 1. 2. The effort would primarily be conducted as a sub-team-like structure within the program and the co-coordinators and drivers of the necessary Artifacts features would be given core-reviewer status temporarily with an informal agreement to merge code that is only related to Artifacts. 3. The entire Glance team would give reviews as time and priorities permit. The approval (+A/+WorkFlow) of any code within the program would need to come from core-reviewers who are not temporarily authorized. The list of such individuals and updated time-line would be documented in phases during the course of Liberty cycle. 4. We will continue to evaluate & update the governance, maturity of the code and future plans for the v1, v2 and v3 Glance APIs as time progresses. However, for now we are aiming to integrate all of Glance (specifically Images) as Artifacts in the v3 API. As I understand it, that is to say that v3 requests in the first "micro-version" that specify the object type as image would get a not implemented or similar error. The next next "micro-version" would likely contain the support for images along with possibly implementing the v1 and v2 APIs on top of v3. 1. Special thanks to Flavio for providing DefCore and TC perspective as well as initializing this discussion. Also, thanks to Stuart McLaren and Brian Rosmaita for giving us thoughtful veteran feedback. The entire team did a great job at putting all their questions and concerns amicably on the table and came to a good understanding of the plan and level of commitment. All the best to the Project SearchLight team who have decided to start ElasticSearch based development for search functionality in OpenStack as a separate program and would be porting respective code out of Glance. Glance team would help co-ordinate this porting effort in order to avoid destabilizing Images and MetaDefs code-bases. This also means we will re-evaluate some of the existing spec proposals and most likely not ask people for radical changes in their approach. This first phase of the Liberty cycle would focus on seeing the Experimental Artifacts API through. We will also focus on stability aspects of the Images (v1 & v2) related features. The second phase priorities would be decided at the mid-cycle meet-up (details to come out soon). Feel free to ask me questions on IRC or via email. Cheers, Nikhil
