  • Agents no longer publish data globally. Global publishing of data by agents causes security and scaling issues. In QMFv2, the global publish is replaced by subscription queries where a console establishes a subscription and receives periodic updates about changes to data in its field of interest. The benefits are that the query can be authorized based on an authenticated user-id and that data is not generated if there are not consoles interested in receiving that data.
