----------------------------------------
Summary: Allow for parallel calls on ManagedService(Factory)#update
Key: FELIX-5438
URL: https://issues.apache.org/jira/browse/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
concurrently).
However after looking at UpdateThread.java 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)
services.
Is there any design rationale why this is the case?
