Intro

This page describes the intent to implement oslo messaging's API Version Negotiation in Trove

Oslo

Oslo/Messaging#API_Version_Negotiation

Goals

  • Prevent backward incompatibility between Trove components.
  • Reduce the need for downtime during deployments

Work

  • Keep track of a "version history" in comments in the code
  • Update trove calls to the openstack.commom.rpc client to include a version cap param. (This is already supported in the client)
  • Document the use cases and examples of how to add/modify API calls
