> The incorporation of AGPLv3 code Into OpenStack Project is a >significant decision
To be clear, Marconi does not incorporate any AGPL code itself; pymongo is Apache2 licensed. Concerns over AGPL were raised when Marconi was incubated, and I totally respect that some folks are not comfortable with deploying something like MongoDB that is AGPL-licensed. Those discussions precipitated the work we have been doing on SQLAlchemy and Redis drivers. In fact, the sqla driver was one of the graduation requirements put in place but the TC. Now, if people want to use something else than what the Marconi team is already working on, we are more than happy to have them contribute and help us evolve the driver interface as needed. On the subject of minimizing the number of different backends that operators need to manage, some relief may be found by making the backends for projects more customizable. For example, as we move more projects to using the oslo caching library, that will give operators an opportunity to migrate from memcached to, say, Redis. And if OpenStack Service X (Marconi, for example) supports Redis as a backing store, now the operator can reuse their Redis infrastructure and know-how. The software industry has been moving towards hybrid NoSQL+SQL architectures for a long time now, in order to create best-fit solutions; I think we’ll see more OpenStack projects following this model in the future, not less, and so we need to work out a happy path for supporting these kinds of operating environments.
