Forgive the top-post.
Cross-posting to openstack-operators for their feedback as well.
Ed the work seems very promising, and I am interested to see how this
evolves.
With my operator hat on I have one piece of feedback.
By adding in a new Database solution (Cassandra) we are now up to three
different database solutions in use in OpenStack
MySQL (practically everything)
MongoDB (Ceilometer)
Cassandra.
Not to mention two different message queues
Kafka (Monasca)
RabbitMQ (everything else)
Operational overhead has a cost - maintaining 3 different database
tools, backing them up, providing HA, etc. has operational cost.
This is not to say that this cannot be overseen, but it should be taken
into consideration.
And *if* they can be consolidated into an agreed solution across the
whole of OpenStack - that would be highly beneficial (IMHO).
Just because they both say they're databases, doesn't mean they're even
remotely similar.
True, but the fact remains that it means operators (and developers) would have
to become familiar with the quirks and problems of yet another piece of technology.
