See https://docs.google.com/document/d/16PFU3OpjMvnYjILAY00FlnabfUyIOWOPR-1tTFh_I10/edit?ts=60129a42 This issue corresponds with phase 4 of the transition plan. Between the database and the incremental engine, there needs to be logic to filter out non-local data. This task can be done in parallel with issue #1922489
Prioritizing this "low" because since this issue was opened, the idea of an ovn-controller refactor has fallen way down the list of important things. Changes in ovn-controller have made it perform light years better than it used to. While it's still in need of cleanup, we don't also have the increased performance angle to lean on. In fact, it's possible that the refactor on its own would cause performance regressions initially, since the focus would mainly be on writing error-free clean code.
