However, our major concern for Orbeon Multitenancy is scalability. If you're going multi-tenant, make sure you test this early ;-).

Biggest problem with getting it to a scalable state so far is that for some things, orbeon seems very slow (pdf generation and email sending, among others), Although this may be related to form-size of our test forms; performance will need to be watched carefully if we want to achieve sublineair scalability and a good end user experience.

Agreed.

Also: security: role-based is very necessary, but the addition of user-based, as discussed in another thread, is something that will probably be have to added in multi-tenant environment.

Absolutely.

On that, I was curious: how hard would it be to make a version of the fr summary view that shows a user's submissions accross forms, instead of a form's across users? Supposing the persistency layer would already be built to support it and provide a restfull interface endpoint like POST "/search/username[optional: /app/form]"

Not "too" hard ;) I can see how to do it. The main issue is that I think we should use this opportunity to reorganize the code of the Summary page, which as a bit too much "history" by now. But it's going to be post-4.0.

Yes I think you could assign to each client a Form Runner "app", and target a different database for each. -Erik On Thu, Jun 28, 2012 at 7:47 AM, Jan Penninkhof <[hidden email]> wrote: > You are totally right.
