Re: [higgins-dev] IdAS update proposals

On transactions ...

As a general principal, I don't want to pay the overhead of certain 
functionality in Higgins, but I want to make sure its possible/practical 
to add it to derived products. So load balancing/clustering, real audit, 
real access control, real transactions all need to be supportable in 
derived products - but don't need to be fully supported in the reference 
implementation. We do however, need to put the plug points into the 
reference implementation so these enterprise level capabilities can be 
added without modifying existing code. 

In the case of transactions, we'd likely want multiple operations to be 
part of the same transaction. For instance, an update that crosses 
multiple contexts, or one that must be audited should include the commit 
of an associated audit record.

So I think we should consider separating the Transaction into its own 
interface, which can be passed into various update methods. I know this 
introduces a lot of complexity, and I would not want to add it until we've 
discussed it at length (probably a f2f agenda item), but its something we 
need to consider.

Thanks,
Mike
