             Summary: Allow for parallel calls on ManagedService(Factory)#update
                 Key: FELIX-5438
             Project: Felix
          Issue Type: Improvement
          Components: Configuration Admin
    Affects Versions: configadmin-1.8.12
            Reporter: Magnus Jungsbluth

I have been using the ConfigAdmin implementation a while now and I was always 
under the assumption that ManagedService(Factory)S were called in parallel 
(with the restriction that per MSF instance updated() cannot be called 

However after looking at it became clear that ALL updates to 
ManagedService(Factory)s are sequentially applied. In our system this led to a 
situation were a timeout of a very early ManagedServiceFactory triggered a 
cascade of other timeouts that made it very unclear what the root cause was 
especially cause these parts of the system were completely independent (despite 
all using ManagedServiceFactoryS).

I also suspect that this can impact startup performance when using MS(F) 

Is there any design rationale why this is the case?
