So, I can't confirm. What I have learned with this experiment is: 1) Yes, EOF can handle a multi tenant architecture with a single model and multiple databases/stacks. I haven't faced any technical problems fetching, creating and editing data using this architecture. 2) Yes, memory consumption is higher if compared to a multi tenant architecture with single model and single database. But it is much better than the sum of the memory consumed by each application in a single application per tenant approach. 3) No, EOF is not optimized for this architecture. A superficial analysis of memory consumption even in that simple example reveals some points for optimization in the EOF code. Certainly, EOF could handle this architecture in an improved way after a few hacks. :) In conclusion, if the number of expected tenants per application is relative low (let's say up to 50 tenants) this approach is reasonable. If the number of tenants is expected to be much higher then it is impracticable without optimizations.
