One of the things that came out of the PTG was perhaps a new path forward on hierarchical limits that involves storing of limits in keystone doing counting on the projects. Members of the developer community are working through all that right now, that's not really what this is about.
As a related issue, it seemed that every time that we talk about this space, people jump into describing how they think the counting / enforcement would work. It became clear that people were overusing the word "overbooking" to the point where it didn't have a lot of meaning. https://review.openstack.org/#/c/441203/ is a reference document that I started in writing out every model I thought I heard people talk about, the rules with it, and starting to walk through the kind of algorithm needed to update limits, as well as check quota on ones that seem like we might move forward with. It is full of blockdiag markup, which makes the rendered HTML the best way to view it - http://docs-draft.openstack.org/03/441203/11/check/gate-keystone-specs-docs-ubuntu-xenial/c3fc2b3//doc/build/html/specs/keystone/backlog/hierarchical-quota-scenarios.html There are specific question to the operator community here: Are there other models you believe are not represented that you think should be considered? if so, what are the rules of them so I can throw them into the document. Would love to try to model everything under consideration here. It seems like the conversations go around in circles a bit because everyone is trying to keep everything in working memory, and paging out parts. Diagrams hopefully ensure we all are talking about the same things. -Sean -- Sean Dague http://dague.net _______________________________________________ OpenStack-operators mailing list OpenStack-operators@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-operators
