Hi Bram, As far as I can see, the use case I mentioned in november last year is not fully covered. In the case of using Cassandra for storage (but same applies to other storage implementations) we have a Cassandra keyspace associated with one particular tenant. When a new tenant (service) comes available, we add a keyspace if it does not yet exist. But in the current approach I don't see anything that tells me the tenant has been deleted; there is no difference between the tenant service being stopped and permanently removed. The same question applies to creating backups for tenants. How can I implement 'delete tenant' and 'backup tenant' features for my storage engine? A full working code example with the new approach would be nice.

This included (partially offline) discussions on what we will and wont cover as well as how we will implement it. In a nutshell, comparing to the "old"model the goal is to come up with a solution that is optional, transparent/non invasive, still very flexible and ready for provisioning. The results are covered in the pages listed below providing an architectural overview [0], requirements [1], use-cases [2] and a more detailed design[3]. This is not the end and it is not a done deal as over the next couple of weeks we will spend some more iterations to refine, implement and proof the model. Therefore at this point we would very much appreciate feedback from the community and specifically anyone interested in Multi-Tenancy. Do you feel requirements and use cases cover your needs? Do the design and proposed implementation make sense? Any feedback will be most valuable to our end goal, which is to come up with a stable future proof model for 1.0!
