Schema and Schema Validation for Notifications

Sign up or log in to save this to your schedule, view media, leave feedback and see who's attending!

Notifications emitted from OpenStack Services have a small number of required fields: event_type, timestamp and priority. The rest goes in an undefined "payload" section. As OpenStack has grown we've seen the need to enforce the schema of these payload sections as well as establish some consistency rules for notifications. This session will define a plan for implementing this schema validation as well as how to deprecate the old notification scheme (or provide an alternative). The challenge to migration is updating all the code in all the OpenStack services which hand-crafts the payload data. What will happen to existing downstream systems that expect the current format?

Session Leads: Sandy Walsh, Julien Danjou
