The node traits feature [1] is an essential priority for ironic in Queens, and is an important step in the continuing evolution of scheduling enabled by the placement API. Traits will allow us to move away from capability-based scheduling. Capabilities have several limitations for scheduling including depending on filters in nova-scheduler rather than allowing placement to select matching hosts. Several upcoming features depend on traits [2]. Landing node traits late in the cycle will lead to less time being available for testing, with a risk that the feature is release with defects. There are changes at most major levels in the code except the drivers, but these are for the most part fairly isolated from existing code. The current issues with the grenade CI job mean that upgrade code paths are not being exercised frequently, and could lead to additional test/bug fix load on the team later in the cycle. The node traits code patches are all in review [3], and are now generally getting positive reviews or minor negative feedback. rloo and TheJulia have kindly offered to review during the FFE window.
