Hi,
We have cases where we need to process events with different priorities,
and such priority can change after the initial event having been queued,
but not yet processed.
For example, when there is an event that some content has changed, we

Hi,
We are using push streams to process post-commit events. Those events
originate from different data sources. At the moment we are processing
those individually, but the overhead of having a transaction for each is
too much. Quite often those events come in bursts following an upstream
citizen.

Ok,
After another 10 hours of frustration, I finally solved the issue. By

We ended up with an exception thrown in the forEach of our stream, which is
a stream to manage notifications and that should be always on. Nothing got

Tim,
Circling back on this. Re-reading section 112.3.6 it says "This means that
if a component instance used a Component Service Objects object to obtain
service objects, SCR must track those service objects so that when the
service becomes unbound, SCR can unget any unreleased service objects".

Just a small note, I should have stated that my worry is about the unget

Tim,
This helps quite a bit and clarifies a few points for me. As someone who is
migrating from a pre-DS environment and dealing with lots of legacy, how
can prototype scoped services be used outside of DS? That would be
fantastic. Right now we have a good solution to use singleton services

get the feeling that CSO should be favored, but I saw an old post from

When using factory components, you get a ComponentInstance and you should

Working through our move from RCP to a generic OSGI solution, and I am

There was an issue a while ago for EMF that resulted in a generation
setting to support generic OSGI frameworks and not only Eclipse/Equinox.
But the resulting bundles still have plugin.xml

Facing an issue and looking for the right pattern to apply where I have a
service interface that is extended and at run time I want to always run the
most appropriate one. Each extension provides additional method to the API.
