Hi all, To add to this, there was a concern on the footprint of MB running inside carbon servers. And, as discussed MB+Cassandra is not what's going to be used here, but probably another mode. There will be 3 modes in total:
1. In-memory 2. SQL-DB 3. Cassandra The Embedded-MB will be like an Embedded Registry or AM, and will be a minimal deployment to support basic requirements. Further, MB is not simply used for DepSync but also for several platform-wide requirements and as a part of the unification process we are working on. For example, Notifications will use this too. Thanks, Senaka.
