Angelo van der Sijpt commented on AMDATU-130:
---------------------------------------------
I like the term SSE :) It does, however, deserve its own issue, which we can
use to flesh out the interface.
For the non-core bundles, they still should not rely on Cassandra, unless they
are sure they will _only_ be used in combination with Cassandra. So, the
Shindig and Profile service should have their own abstraction for storage, for
which we can supply a SSE-based implementation.
The courses services, I'm not so sure. It is an example service, after all, it
all depends on whether we feel like supporting it until kingdom come.

> Services that are considered to be part of the "Amdatu Core" should not rely
> on the availability of some sophisticated storage like Cassandra. Currently
> this is the case, for example the UserAdmin store depends on Cassandra. No
> choice on what storage engine should be used has been made yet. However, say
> we choose for the storage engine "SSE" (SimpleStorageEngine). Then the
> following changes are necessary:
> - Add a UserAdmin storage implementation for SSE. Note that the cassandra
> implementation will be moved to the cassandra subproject.
> - The Tenant service should store Tenants by default in SSE. The cassandra
> implementation will be moved to the cassandra subproject.
> - Implement a ConfigurationAdmin that persists using SSE (currently it
> persist in the bundle cache)
> Furthermore, maybe the following non-core components should be updated too:
> - The Shindig opensocial container and gadget management service should store
> all info (i.e. Gadgets, AppData) in SSE. What to do withe the cassandra
> implementation?
> - Same for the profile service
> - The course service example should also provide an example for SSE storage
