[~chetanm], thanks for the suggestions. I applied all of them in
[r1761799|https://svn.apache.org/r1761799].
What about the SegmentNodeStoreService? Do you think we should make it
consistent (as in OAK-4834) or once we have the factory we don't need the
NodeStoreProvider capabilities in the "main" service?

[~tomek.rekawek] Would suggest some changes here
* directory - Component should not assume any default here. Or have default
based on role name otherwise they would step on each other
* For "secondary" role I would set {{customBlobStore}} to be true to ensure
that it used the BlobStore used by DocumentNodeStore
* May be some basic test coverage

Tomek Rękawek commented on OAK-4655:
I attached a [slightly modified|^OAK-4655.v2.patch] version that allows to set
any {{role}} for the NodeStoreProvider (using {{nsProvider.role}} property).
It's consistent with my proposal to update SegmentNodeStoreService in OAK-4834.
[~egli], could you take a look on the change and say if you are ok with it? If
so, I'll merge the patch, this feature would be very useful in many different
areas of Oak. It also disabled by default, so I guess it's quiet safe to have
it committed.

[~mduerig] [~alex.parvulescu] [~frm] Thoughts around above requirement.
I was thinking to go for an OSGi factory component which (separate from current
SegmentNodeStoreService) which can register a {{NodeStoreProvider}}. We would
also need to ensure that any JMX and Metric registered does not collide
